### Kth Smallest Instructions

Find the minimum number of k-length bit flips to make an array of all 1s or kth smallest string of instructions to reach the bottom-right corner of a grid ### Substring With Largest Variance

Given a string and an integer k, the problem is to find the substring of length k that has the largest variance of character frequencies in it ### Split Message Based on Limit

Given a string and an integer limit, the problem is to split the given string into a list of strings such that the length of each string does not exceed the given limit and return the list ### Find Minimum Time to Finish All Jobs

Given an array of jobs where each job has a start time, end time and a penalty if it is not finished on time, the problem is to find the minimum penalty that can be incurred by finishing the jobs in the order they are given ### Minimum One Bit Operations to Make Integers Zero

Given an array of integers, the problem is to find the minimum number of operations needed to make all the integers in the array 0 by performing only one bit operation (flipping one bit) at a time
