The function combinationSum(candidates, target) finds all possible ways to reach the target using given numbers, allowing repeats. How it works: We sort the array and use recursion to explore combinations. If the sum becomes zero, we store the combination. If it goes negative, we backtrack. We loop through candidates, adding numbers..."}
