Question 1

Given a time (24 hours format) with missing digits marked as ‘?’. Return the latest possible time.

Examples:

??:?? ==> 23:59

12:23 ==> 12:23

1?:43 ==> 19:43

public static String solution(String T){

// implement your solution here

}

Question 2

Array X is greater than Array Y if the first non-matching element in both arrays has a greater value in X than in Y.

X = [1, 3]

Y = [1, 2]

Given an array A with N integers and an Integer K, return the largest contiguous subarray of length K from all contiguous subarray of length K.

Example:

A = [1, 4, 3, 2, 5], K = 4

return

[4, 3, 2, 5]

public static Integer[] solution(Integer[] N, int K){

}
