#1) Prompt user for sentinel value

#2) Store sentinel in t0.

#3) Begin loop. 
	#a) prompt user for integer value
	#b) store it in t3 #skip this step, as the program instructions ask us not to save the number. we can just keep it in v0 until we're done with it
	#c) If t3>0 add 1 to s0, if t2<0 add 1 to s1, if t2 = 0 add 1 to s2. 
	#d) If t3>0 add it to t1, if t3<0 add it to t2. We can combine this with 3c. 
	#e) Set t3 = 0.
	#f) go back to the start of the loop
	#g) exit the loop if sentinel is entered	

#4) Output
	#a) Output sums 
	#b) Output counters
	#c) Comparison and ouput phases
	#	i) Compare positive and negative, if positive go to ii, else go to iii
	#	ii) compare positive and zeroes, output 
	#	iii) compare negative and zeroes, output

#5) Terminate
