	#	Then call a_to_i to perform conversion from string to integer
	#	Then use syscall 1 to print the integer result

a_to_i:
	#----------------------------------------------------------------#
	# $a0 has address of the string to be parsed.
	#
	# Write code here to implement the function you wrote in C.
	# Since this is a leaf procedure, you may be able to get away
	# without using the stack at all.
	#
	# $v0 should have the integer result to be returned to main.
