679. 24 Game

Leetcode Solutions

Define a helper function generatePossibleResults(a, b) that returns all possible results of operations between two numbers a and b.
Define the main recursive function checkIfResultReached(list) that tries to reach the result 24 using the current list of numbers.
- If the list has only one number, check if it is approximately 24 and return the result.
- Otherwise, for each pair of numbers in the list, perform all operations and recursively call checkIfResultReached with the updated list.
- If the recursive call returns true, propagate the success; otherwise, backtrack.
Start the algorithm by calling checkIfResultReached with the initial list of cards.
