(ASSEMBLY CODING) Write 'ACCOUNT_KEY' subroutine that counts how many times a key is present in a sequence of digits. The subroutine receives: R3 = start address of the Key (KEY) to be fetched; R4 = Sequence start address (SEQ) where to look for the Key. R5 = how many times the Key (KEY) is present in the Sequence (SEQ). Note that the numbers are represented in ASCII and that the end of SEQ and KEY is characterized by the ZERO byte. For simplicity, assume that only ASCII codes of numbers are present.
