PROBLEM:
Moengage helps the Chef send email reminders about rated contests to the participants.
There are a total of N participants on Chef’s platform, and U of them have told Chef not to send emails to them.
If so, how many participants should Moengage send the contest emails to?
EXPLANATION:
For each test case, there are 2 integer inputs N and U denoting the total number of participants on the Chef’s platform and the number of users who have told Chef not to send emails.
Thus, it is clear that (N-U) participants should receive emails from the platform.
TIME COMPLEXITY:
O(1) for each test case.
