## Tech Weekend – ISTE

*in*Event Reports

The first week of February was a very eventful one, thanks to the Tech Weekend held jointly by ISTE and IE Mechatronics. The Tech Weekend celebrated the involvement of technology in our day to day lives. There were various events focusing on different aspects of technology like coding, tech quizzes, and math problems. Bharat Krishna, the Chairperson of ISTE’s Manipal Chapter, said that he expected the Tech Weekend to* “get students active and rather than focus on one particular branch of engineering, include all branches in a fun and wholesome manner.”* The events that took place were the following:

**CODE KRIEG**

The first round of Code Krieg saw the participation of thirty teams over the course of two days, with each team consisting of two members. In this round the teams had to debug certain mind boggling codes written in C/C++. The teams were awarded one point for finding the correct output, two points for pointing out the errors, and another two points for fixing the bug. All of this had to be achieved in the given period of half an hour. From this round, the top ten teams would go on to ‘Code It Out’ in the second and final round.

The second round of Code Krieg was held on Sunday morning. This round had a duration of ninety minutes. The top ten teams from round one were given fifteen questions to answer in the stipulated time. All the questions carried the same weightage and in case of a tie the winner was decided according to who finished first. The questions were based on competitive coding and each team was given only two attempts to get the right output, failing which they had to move on to the next question.

**MATHTRIX**

Mathtrix was the only individual event of this year’s Tech Weekend. Nearly seventy five students took part in the first round of Mathtrix from which sixteen qualified for the final round. The participants had to answer twenty objective questions of one mark each and two subjective questions of three marks each. The questions tested the participant’s knowledge of algebra, data interpretation, calculus, probability, linear mathematics, patterns and sequences.

The second round of Mathtrix was further split into three rounds with eliminations at the end of each round. The first round was an online game of Housie which lasted for thirty minutes, at the end of which eight participants qualified for the second round. The second round involved four small mathematical games. The first game was called ‘Broken Calculator’ wherein the participants were given a ‘calculator’ with certain numbers and operations missing, and they had to get the desired result by using the remaining digits and operations. The second round was called ‘Number Maze’ in which the players had to reach the finishing point of the maze by solving sums. The third game was titled ‘Word Search’ wherein the names of four key concepts of mathematics were hidden in a sea of letters. The participants had to find these four words and had to solve a question pertaining to each of these concepts after doing so. The fourth game was a simple math crossword where the participants were required to solve equations and use the answer obtained to fill in the crossword. This entire round was to be completed in thirty minutes. At the end of this round, four participants moved on to the third and final round. The final round was a quick fire alphanumeric crossword and puzzle round where the participants were given only ten minutes to solve the entire game. The participant with the most number of correct answers was the winner.

**TECH QUIZ**

The tech quiz saw the participation of about twenty teams of two. The first round comprised thirty questions on general knowledge about technology, with one mark being awarded for each right answer. There were also five additional questions to settle any ties. From this round seven teams went on to compete in the second and final round.

The second round of the tech quiz, held at 11 AM on Sunday, went on for a lengthy two hours. This round was further divided into five rounds. The first round was a general quiz wherein each team was asked two questions. Ten points were awarded for every right answer and five for every right answer that was a passed question. The second round was a ‘Picture and Logo’ round wherein each team were shown the logo of a company, a product or the face of a tech giant. The teams were awarded ten points for every right answer while five points were deducted from their score if they answered incorrectly. The third round was titled ‘Who am I?’ in which a team had to guess a company, a software or a person based on certain hints. If they got it on the first hint, the team would be entitled to ten points. Consequently six, four or two points were allotted according to the number of hints they required to answer the question correctly. At the end of the third round, three teams were eliminated and the scores of the remaining four were set to zero. The fourth round was a version of ‘Categories’ wherein four topics, namely History of Tech, Billionaires, Gadgets and Current Tech, were given to the teams. Each topic had four levels of increasing difficulty. The teams were awarded five, ten, fifteen or twenty points depending on the level they choose. At the end of this round, two teams were eliminated and the remaining teams went head to head in the final rapid-fire round. In the final round each team was asked ten questions, which they had to answer in a minute. The winners were Sailesh and Nabil, who answered nine out of ten questions correctly, and the runners up were Dhruv and Baidurya who answered five questions correctly.

**CLUELESS**

Clueless saw the participation of about forty teams with each team comprising two or four members. The first round was a pen and paper round which tested the team members on their IQ, pattern solving skills, acumen and code deciphering skills. The first round lasted for thirty minutes and the top ten teams went on to compete in the second and final round, held on Sunday.

The second round of Clueless went on for a good three hours. This was a mystery solving/treasure hunt round. A crime scene was described to all the contestants which involved a famous painting, called the ‘Art of Madonna’, being stolen from an art gallery. The descriptions and backgrounds of five suspects were given to the teams. The contestants were also given hints as to where they were required to go in order to get the next hint pertaining to the crime and the location of the next hint. They were also required to complete a task at the location and the tasks ranged from blowing a balloon in a bottle to finding a green cloth in a garden to using a divider in a game of darts. The team that failed to complete the task at each location or which did so last was eliminated from the competition. The locations of the hints were as follows: Chemistry Lab in AB1, Venugopal Temple, Recreation Centre, Food Court, Swimming Pool, and finally the Workshop. After this the remaining teams had to come back to NLH and solve a jigsaw puzzle of the aforementioned painting on completion of which the team had to name the culprit from the given list of suspects.

**RECODE**

Round one of Recode saw the participation of close to fifty teams. This was a pen and paper round which tested one’s programming logic in which the participants had to correct the errors and get the required outputs. The questions included MCQs in which the participants were awarded two points for every right answer and negative one for every incorrect one. There was also one alternate logic question for three points. From here the top ten teams proceeded to the final round held on Friday.

The second round of Recode was all about decrypting jumbled up codes. The top ten teams had to slog it out over a period of ninety minutes to get the right password in order to answer the next three questions. Hints were provided to the participants in exchange of deducted points. In order to make things interesting, teams were to execute the code using only the lines mentioned in the jumbled code. The lines could not be edited and new lines could not be added while existing lines could not be deleted. If they got the required output, they won the allotted points.

Thus the Tech Weekend was brought to an end after five days of high voltage competitiveness, drama and fun. Students from all the departments and all the years showed up to take part in this event and they indeed had a lot of fun in the process. We hope that ISTE keeps up the good work and keeps hosting other such marvelous events in the future.
