Question

using Mips assembly to work on Mars simulator

write a program that outputs the maximum and minimum values of an entered array

Answer 1

MIPS Assembly level program that outputs maximum and minimum values of an entered array:

.LC0:
.string "Enter the size of the array : "
.LC1:
.string "Enter the elements of the array : "
.LC2:
.string "Maximum element : "
.LC3:
.string "Minimum element : "
