// where 'n' is the length of 'nums'. // For each number in 'nums', we traverse each position for the permutations to add the number, // with each permutation being O(n!). // Space Complexity : O(n!), ...

Backtracking is a powerful algorithmic technique used to solve problems involving decision making, such as finding a solution to a maze, solving a Sudoku puzzle, or generating permutations of a set.
