Q17 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?MooStartXXXcurrVal Get next inputYYYFALSEEndTRUEZZZcurrval= Get next inputO XXX: sum=0/YYY:not(currVal == 0) / ZZZ: sum = sum + currValO XXX: sum= currVal/YYY: currVal == 0/ZZZ: sum= currValO XXX: sum=1/YYY:not(currVal == 0) / ZZZ: sum - sum +1O XXX: sum - Get next input/YYY: currVal == 0 / sum - Get next input

XXX should be the initialization of sum before we start summing the inputs.YYY should be the loop's continuation condition, i.e., the condition under which the loop keeps running.ZZZ should be the operation that adds the current value (currVal) to sum.XXX: sum = 0 / YYY: not(currVal == 0) / ZZZ: sum = sum + currValThis option correctly initializes sum to 0, continues the loop while the current value is not 0, and adds the current value to sum. This seems like the correct set of operations based on the description.XXX: sum = currVal / YYY: currVal == 0 / ZZZ: sum = currValThis is incorrect because it initializes sum with currVal which is not known at the start, the continuation condition stops the loop when currVal is 0 (which should be the termination condition), and ZZZ does not accumulate the sum but sets it to the current value each time.XXX: sum = 1 / YYY: not(currVal == 0) / ZZZ: sum = sum + 1This option incorrectly initializes sum to 1, which would make the final sum too high by 1. Also, ZZZ incorrectly adds 1 to sum each time instead of the current value.XXX: sum = Get next input / YYY: currVal == 0 / ZZZ: sum = sum + 1This is incorrect because it initializes sum with the first input (which should instead be added to sum), has the wrong continuation condition (should continue when currVal is not 0), and adds 1 instead of the current value to sum.Therefore, the correct answer based on the logic needed is:XXX: sum = 0 / YYY: not(currVal == 0) / ZZZ: sum = sum + currVal
