You are to write an IAS program to compute the results of the following equation. N Y = X=1 Assume that the computation does not result in an arithmetic overflow and that X, Y, and N are positive integers with N 1. Note: The IAS did not have assembly language, only machine language. N(N + 1) a. Use the equation Sum(Y) 2 b. Do it the "hard way," without using the equation from part (a). = when writing the IAS program.
