864. Missing Ranges
Given a sorted array of integers called nums, where the elements range from a lower value to an upper value (inclusive), output the missing ranges in nums.
The first line of input consists of three space-separated integers: N (the size of the array), the lower value, and the upper value. The second line contains the elements of the array nums.
Print each missing range in a new line.
5 0 99 0 1 3 50 75
2 2 4 49 51 74 76 99
1 <= N <= 10^4
