For this homework, you will explore different types of integers. As you know the C $/$ C $++$standard leaves issues such as the number of bits and numeric format up to the compiler $($ unlike some other languages $).$For purposes of this homework, we will assume that long integers are $64$bit twos complement $($ TC $),$and integers are $32$bit TC $.$ Recall that to convert an $-$n bit integer k to a m bit integer where m $>$ n we need to account for two cases:

$1.$If k is negative, concatenate $1$ s to the more significant part. For example, $1011$becomes $11111011($ where n $=4,$m $=8)$

$2.$If k is non $-$ negative, concatenate $0$ s to the more significant part. For example, $0011$becomes $00000011.$ This is called sign extension. Write MIPS code to convert an array A of integers to an array B of long integers. Both arrays have size n $.$ You may treat A $,$B $,$and n as HLL variables. As usual, you are required to both draw a CFG and may only use certain instructions $($ excluding functions $).$Note that we have not covered any instructions dealing with doublewords. You may choose to first write this in C $-$ ish pseudocode though it is not required. But a CFG is required. The instructions you can use are addi, addi, jal, lw $,$sw $,$slti$,$ bne, j $,$jr $,$Ret$,$ RetOne. Only use these, dont use other ones. PLEASE DO ALL WELL, FOLLOW ALL DIRECTIONS, DO FULL MIPS CODE WITH ALL COMMENTS PER CODE, PROPER MIPS, SHOW WHAT YOU ARE DOING BASED ON INSTRUCTIONS SAID. DO A PROPER CFG TOO!! CFG IS A FLOW CHART,do this flowgorithm way
