#$1(3$ points$)$ Given the main below and assuming doubleIt is implemented as well, fill in the implementation for the function foo. Your code should use the ABI names for the registers. main:

li a$0,3$

li al$,2$

jal foo

doubleIt:

# doubleIt doubles the parameter given in a$0$

# and returns it in a$0$

# Assume this function is implemented and works $-$ you do not need to code this function

# You should not assume any details of the doubleIt implementation beyond what is stated above

foo:

# foo shoufd double the values given in both $a0$ and al by calling the doubleIt function twice

# It should then subtract those doubled values and return the result in $a0$

# For example, if $3$ and $2$ were originally passed in from main, it would return $6-4$ or $2$
