You are to write an IAS program to compute the results of the following equation.

$Y={\displaystyle \underset{x=1}{\overset{N}{}}}x$

Assume that the result of the computation does not arithmetic overflow and that $x,Y,$ and $N$ are positive integers.

Use the equation $\frac{?}{\text{S}\text{u}\text{m}}(Y)=N\frac{N+1}{2}$ when writing the IAS program.
