USE SLL

Answer 1

MIPS PROGRAM :-

    .data
       Array:   .word   1,2,3,4,5,6,7,8,9,10
   .text
   .globl main
main:
   addi $t0, $0, 0
   la $t2, Array
LOOP:
   lw $t1, 0($t2)       #retrieiving the value of each element in array
   sll $t1, $t1, 2       #multiplying each element with 4
   sw $t1, 0($t2)   #storing the modified value in array
  
   addi $t0, $t0, 1   #counter++

addi $t3, $0, 10
   bne $t0, $t3, LOOP
  
#program exit
   addi $v0, $0, 10
   syscall
