649. Find All Numbers Disappeared in an Array
Ram needs assistance in finding all the missing numbers from `1` to `n` in the array **nums**. Your task is to help him by providing a **sorted** array of integers in the range `[1, n]` that do not appear in nums.
The first line contains an integer N. The second line contains an integer array of size N.
Print a sorted array of all the missing numbers.
8 4 3 2 7 8 1 2 3
1 <= N <= 10^5 1 <= Nums[i] <= N
