The N Queens Problem involves finding all possible placements of N queens on an N x N chessboard where no two queens threaten each other.
Understand the constraints of the problem: N represents the size of the chessboard and the number of queens, and queens can attack each other if they are in the same row, column, or diagonal.
Implement a backtracking algorithm to explore all possible configurations of queen placem...
Pair Sum Problem Statement
You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to find and return a list of all pairs of elements where each sum of a pair equals 'S'.
Note:
...
Given an array and a target sum, find pairs of elements that add up to the target sum.
Iterate through the array and for each element, check if the complement (target sum - current element) exists in a hash set.
If the complement exists, add the pair to the result list.
Sort the result list based on the first element of each pair, and then the second element if the first elements are equal.
