Equal Beauty CodeChef SnackDown 2021 Round 1A Question The beauty of an (non-empty) array of integers is defined as the difference between its largest and smallest element. For example, the beauty of the array [2,3,4,4,6] is 6−2=4. An array A is said to be good if it is possible to partition the elements of A into two non-empty arrays B1 and B2 such that B1 and B2 have the same beauty. Each element of array A should be in exactly one array: either in B1 or in B2. For example, the array [6,2,4,4,4] is good because its elements can be partitioned into two arrays B1=[6,4,4] and B2=[2,4], where both B1 and B2 have the same beauty (6−4=4−2=2). You are given an array A of length N. In one move you can: Select an index i (1≤i≤N) and either increase Ai by 1 or decrease Ai by 1. Find the minimum number of moves required to make the array A good. Input Format The first line of input contains a single integer T, denoting the number of test cases. The description of T test cases follow. Each ...
Why is Coding tough to learn in schools Coding is easy but the way it is taught in schools makes it look difficult. This question arises in all students who start learning coding and find it difficult and start hating it. Trust me it's not hard there are just few reason for coding to look difficult: Since Coding is a new field so teachers who were graduated before coding went on boom have less knowledge about this field. Programming Languages which are taught in school are high-level languages like Java, C++ etc which are quite difficult to understand at the start. Next issue is if some senior had difficulties in coding said you that coding is very difficult and that's the reason you are imagining it difficult. To do coding you just need a bit of logic and a good teacher. This will make your journey of coding easy and smooth. Easiest Languages you should learn 1) HTML 2) Python 3) Go The ideal roadmap for learning programming is given below: Thus we conclude that coding is not...
