The Pep/9 assembly code below is a students implementation of the following algorithm for positive integer N. While (N>1) { if N is even N=N/2 otherwise N=3*N+1 } Circle or otherwise identify the redundant instructions top: ldwa 0,i ldwa N,d cpwa 1,i breq done br test test: ldwa N,d anda 1,i breq even brne odd even: ldwa N,d asra stwa N,d br next odd: ldwa N,d adda N,d adda N,d adda 1,i next: stwa N,d breq even br top done: stop
