What is the shortest sequence of MIPS instructions that extracts a field for the constant values of bits 7-21 (inclusive) from register $t0 and places it in the lower order portion of register $t3 (zero filled otherwise)?

What is the shortest sequence of MIPS instructions that extracts a field for the constant values of bits 7-21 (inclusive) from register $t0 and places it in the lower order portion of register $t3 (zero filled otherwise)? - sll$t0, $t3, 9# shift $t3 left by 9, store in $t0

srl $t0, $t0, 15# shift $t0 right by 15

Explanation:

The shortest sequence of MIPS instructions that extracts a field for the constant values of bits 7-21 (inclusive) from register $t0 and places it in the lower order portion of register $t3 (zero filled otherwise) is shown below:

sll$t0, $t3, 9# shift $t3 left by 9, store in $t0

srl $t0, $t0, 15# shift $t0 right by 15

i'm pretty sure data is stored in a form

i've had the same problem. i generally just ignore it, as a ton of these "verified answers" are completely wrong.
