Notes:

  Matlab: sum(1:100)

  Python: sum(range(1,101))

  Matlab: i = 0; sum = 0; while( i < 100) i = i+1; sum = sum+i; end

  Python: i = 0; sum = 0; while( i < 100): i = i+1; sum = sum+i

  C, C++, Java: int i = 0, sum = 0;  while( i < 100) { i = i+1; sum = sum+i; } // or: ++i; sum += i;

  alt: (101*100)/2

        1 + 2 + 3 + ... + 99 + 100  =  1+100 + 2+99 + 3+98  + ... + 50+51

                                    =  101 * 50  =  5050


       1 +     2 + ... + N-1 +   N  =  Sum

       N +   N-1 + ... +   2 +   1  =  Sum
       ---------------------------
       N+1 + N+1 + ... + N+1 + N+1  =  Sum + Sum  =  (N+1) * N

                               Sum  =  ((N+1)*N) / 2
