// Function signature: def find_missing_number(nums) -> int

// Input:

// An array of distinct integers, where 1 <= len(nums) <= 1000 and 0 <= nums[i] <= len(nums).
// Output:

// An integer representing the missing number in the array.
// Example:
// nums = [3, 0, 1]
// result = find_missing_number(nums)
// print(result)  # Output: 2
// In this example, the function should return 2 since 2 is the missing number in the array [0, 1, 3].

nums = [3, 0, 1]

        if(nums[i] !== i){
