Given an arrayxof sizen > 3and an integerN, return the indices of three elements in the array that sum up to the given integerN. If there is no such triplet, return -1. For example, givenx = [1 4 2 5 8 10]andN = 17, the function should return[2 4 5]becausex(2) + x(...

Write a C program to find the first missing positive integer in an unsorted array using constant space. Write a C program to rearrange an array so that each index contains its corresponding positive integer, then find the missing one. Write a C program to identify the smallest missing ...
Given a maze in the form of a rectangular matrix, filled with either `O`, `X`, or `M`, where `O` represents an open cell, `X` represents a blocked cell, and `M` represents landmines in the maze, find the shortest distance of every open cell in the maze f
