949. Largest Time for Given Digits

Leetcode Solutions

Sort the input array in descending order to ensure permutations are generated in lexicographic order.
Generate all permutations of the sorted array.
For each permutation: a. Construct a time string in the format HH:MM. b. Check if the constructed time is valid (i.e., HH < 24 and MM < 60). c. If valid, compare it with the current max_time and update max_time if necessary.
After checking all permutations, return max_time if it's not an empty string; otherwise, return an empty string indicating no valid time could be made.
