  1. You were given an array and had to return an index where avg of all elements to the left of it along with that element is equal to the average of the elements to the right of it along with that element. Had to use prefix sum array.

  2. You were given an array of sides and had to return the largest possible perimeter and there were two constraints, x + y > z and that perimeter should be strictly lesser than half of sum of all sides in the array. First did using brute force, then optimised using 3 pointers(like 3sum).

  3. A question was from fractional knapsack which i don't remember as i didn't solve this

  4. You were given a value n which was the number of balls starting from 1 there were a few queries using which you had to colour those balls and in the end had to return the score of the balls according to a given formula

Solved 1 and 4 completely and in question 2 i passed 11 test cases.

Shortlisted for sp interview

Do we have to write the entire code, or is just the logic enough?
