Divide a String Into Groups of Size k solution leetcode:- A string s can be partitioned into groups of size k using the following procedure: The first group consists of the first k characters of the string, the second group consists of the next k characters of the string, and so on. Each character can be a part of exactly one group. For the last group, if the string does not have k characters remaining, a character fill is used to complete the group.

Crying Colours solution codechef- You have a total of 3N3N balls of colours RedRed, BlueBlue and GreenGreen. There are exactly NN balls of each colour. These 3N3N balls are now distributed to 33 boxes such that each box contains exactly NN balls. You are given the contents of each box. You would like the 1st1st box to contain all the red balls, the 2nd2nd box to contain all the green balls, and the 3rd3rd box to contain all the blue balls. Note that the given order of boxes is important here — it is not enough for each box to contain only balls of a single colour. To achieve this, you can perform the following operation several (possibly, zero) times

Harshikaa and the Rain solution codechef- There is a tree with NN nodes numbered from 11 to NN outside Harshikaa’s house. The tree is rooted at node 11. Initially the tree was dry, there were no raindrops on any node of the tree. Suddenly it started raining, and every second a drop falls on all the leaf nodes of the tree. Also, every second any drop which wasn’t already on the root node moves one node closer to the root. Sometimes, strong winds shake the tree and all drops which were not on the root fall off. It is known that the wind will shake the tree MM times at A1,A2,…AMA1,A2,…AM seconds after it started raining. If multiple events happen at the same second, they are in this order:
