Backtracking is the process whereby a certain number of steps are revisited, sometimes in a reverse order, in order to retrace one's steps.
Recursion is used for backtracking
The time complexity of the backtracking algorithm is typically exponential, O(2n), where n is the size of the problem.
The expected backtracking runtime for solving this problem is O(2n), where n is the number of decision points in the problem.
The time complexity of backtracking algorithms is typically exponential, meaning the runtime grows rapidly as the input size increases.
Backtracking is a general algorithmic technique that involves systematically trying all possible solutions to find the correct one, while depth-first search (DFS) is a specific graph traversal algorithm that explores as far as possible along each branch before backtracking. In essence, backtracking is a broader concept that can be used in various problem-solving scenarios, while DFS is a specific application of backtracking in graph traversal.
Usually through logic and backtracking.

Backtracking allows for a systematic way of exploring all possible solutions to a problem. It can efficiently prune branches from the search space that do not lead to a valid solution, leading to faster computation. Additionally, backtracking is particularly useful for problems that involve making a sequence of decisions or choices.
Backtracking is a technique used in programming to systematically search for a solution to a problem by trying different paths and backtracking when a dead end is reached. It is commonly used in algorithms like depth-first search and constraint satisfaction problems to efficiently explore all possible solutions.

Backtracking is a method used in problem-solving to systematically explore all possible solutions by trying different options and backtracking when a dead end is reached. This approach helps efficiently find the correct solution by eliminating incorrect paths along the way.
