A permutation is a rearrangement of the elements in a list. A string/array of length n has n! permutation. Input: An array // [‘A’, ‘B’, ‘C’] Output: [‘A’, ‘B’, ‘C’] [‘A’, ‘C’, ‘B’], [‘B’,...

You are given an array of strings. Each of these strings is made up of bracket characters only : ‘(‘, ‘)’, ‘{‘, ‘}’, ‘[‘, ‘]’. Programming languages utilize these brackets in balanced pairs, so...

Problem: Given a number X, flip it to -X. Time complexity : O ( X ) Logic : The negation can be implemented by adding -1, X times. Solution :

Input: An array of n integers and given a number X. Expected output: All the unique pairs of elements (a, b), whose summation is equal to X. Example <pre>Given<span class=”pl-k”>var</span> unSortedArr <span class=”pl-k”>=</span> [<span...
