A loop should sum all inputs, stopping when the input is 0. If the input is 2 4 6 0, the final value of sum should be 12. What should XXX, YYY, and ZZZ be?
Moo
Start
XXX
currVal Get next input
YYY
FALSE
End
TRUE
ZZZ
currval= Get next input
O XXX: sum=0/YYY:not(currVal == 0) / ZZZ: sum = sum + currVal
O XXX: sum= currVal/YYY: currVal == 0/ZZZ: sum= currVal
O XXX: sum=1/YYY:not(currVal == 0) / ZZZ: sum - sum +1
O XXX: sum - Get next input/YYY: currVal == 0 / sum - Get next input
