if more than one number are missing then ?

[NarasimhaRaoVasireddy-rv]

I have a doubt, In the for loop we are finding the SUM of given array which is cool, When we are doing the n(n+1)/2 formula- Here also we are checking the sum of nums array only (nums.length). I think we need to do do int n= nums.length+1; then int actualSum= (n*(n+1))/2 works. Is this approach correct. How it is showing correct output in your code is my confusion.
