PROBLEM:
N students want to attend a cricket match that has M tickets available. How many of them will miss out?
EXPLANATION:
If M \geq N, then all the students can buy tickets, so the answer is 0.
If M \lt N, then N-M of the students won’t be able to buy tickets.
This can be succinctly represented by the formula \max(0, N-M).
TIME COMPLEXITY
\mathcal{O}(1) per test case.
CODE:

for _ in range(int(input())):
n, m = map(int, input().split())
print(max(0, n - m))
