In the field of computer science, solving optimization problems efficiently is crucial for developing optimal algorithms and systems. One such problem is minimizing the XOR (exclusive OR) of pairs in an array to make it a palindrome. This situation holds significance because it offers a chance to determine the optimal approach towards reordering items within an array, which can lead to lower XOR value and creation of palindromes. This essay examines two methods that utilize C++ programming language for resolving this predicament. Syntax To begin with, let's define the syntax of the function we will be using in the following ... Read More

Good problem-solving in computer science heavily relies on efficient algorithms like the Greedy-Best First Search (GBFS).

A palindromic string is a string that is equal to its reverse string. We are given a string that contains ‘0’, ‘1’, and ‘2’ and an array Q of length N and each index of the given array indicates a range in the form of pairs. We have to find the minimum number of characters that are needed to replace in the given range such that none of the palindromic substrings remains in that range. Sample Example Input1: string s: “01001020002”, int Q = {{0, 4}, {2, 5}, {5, 10}}; Output: 1 1 3 Explanation For the range ... Read More
