Question
1) MARIE is a minimalist accumulator architecture that is fully functional. Therefore, it is important to be familiar with it. Name all the registers in MARIE and describe the purpose of each of them.
2) Hand assemble the following program in two passes using the table of MARIE’s opcodes. (remember to convert the opcodes to hexadecimal). Show the values stored in the symbol table.

def foo(): n,m=map(int,raw_input().split()) a=[] for i in range(n): a.append(map(int,raw_input().split())) for i in range(m): for j in range(i+1, n): # ensure j > i a[i][j],a[j][i]=a[j][i],a[i][j] for i in a: #printing transpose print i
