Problem Statement A subarray of array a is defined as a contiguous block of a’s elements having a length that is less than or equal to the length of the array. For example, the subarrays of array a = [1, 2, 3] are [1], [2], [3], [1, 2], [2, 3], . . . Read more

Problem Statement You are given an array of integers and must compute the maximum difference between any item and any lower indexed smaller item for all the possible pairs, i.e., for a given array ‘a’, find the maximum value of a[j] – a[i] for all i, j where 0 ≤ . . . Read more

Problem Statement Two strings are anagrams if they are permutations of each other. For example, “aaagmnrs” is an anagram of “anagrams”. Given an array of strings, remove each string that is an anagram of an earlier string, then return the remaining array in sorted order. For example, given the strings . . . Read more

Problem Statement A string is said to be a special palindromic string if either of two conditions is met: * All of the characters are the same, e.g. aaa. * All characters except the middle one are the same, e.g. aadaa. A specialpalindromic substring is any substring of a string . . . Read more

Problem Statement Alice is taking a cryptography class and finding anagrams to be very useful. We consider two strings to be anagrams of each other if the first string’s letters can be rearranged to form the second string. In other words, both strings must contain the same exact letters in . . . Read more
