1.) Maximum subarray size, such that all subarrays of that size have sum less than k:
-------------------------------------------------------------------------------------
Given an array of n positive integers and a positive integer k, the task is to find the maximum subarray size such that all subarrays of that size have the sum of elements less than k.

3.) Longest Span with same Sum in two Binary arrays :
-----------------------------------------------------
Given two binary arrays, arr1[] and arr2[] of the same size n. Find the length of the longest common span (i, j) where j >= i such that arr1[i] + arr1[i+1] + …. + arr1[j] = arr2[i] + arr2[i+1] + …. + arr2[j].

5.) Minimum cost for acquiring all coins with k extra coins allowed with every coin:
---------------------------------------------------------------------------------
You are given a list of N coins of different denominations. you can pay an amount equivalent to any 1 coin and can acquire that coin. In addition, once you have paid for a coin, we can choose at most K more coins and can acquire those for free. The task is to find the minimum amount required to acquire all the N coins for a given value of K.
