Suppose we have an array A with n elements. In a coding contest, in total n students will participate, and before the start, every one of them has some positive rating (integer). A[i] represents the rating of ith student. After the contest ends, every student will end up with some ... Read More

Suppose we have an array A with n elements. A has elements either 0 or 1. There is a tree. In consecutive n days, if A[i] is 0 it is not watered, if it is 1 then it is watered, the flower grows in the following manner −If the tree ... Read More

Suppose we have a number n. We want to split it into some non-zero digits whose sum is n. We want to find a solution with minimum possible number of different digits.So, if the input is like n = 13, then the output will be [1, 1, 1, 1, 1, ... Read More

Suppose we have a number m and a nested list A with n sub-lists. Consider there are m bulbs, initially all are turned off. There are n buttons and each of them is connected to some set of bulbs. So A[i] is the set of bulbs that can be turned ... Read More
