समस्या
A year divisible by 4 is a leap year unless it is also divisible by 100. Years divisible by 400 are leap years despite that exception. Apply this arithmetic rule to every allowed input year.
Implement leap_year(year).
Input
year: The year to check.
Output
Return true for a leap year and false otherwise.

1 ≤ year ≤ 9999.
उदाहरण
इनपुट:
year = 2024
अपेक्षित आउटपुट:
expected = Trueइनपुट:
long long year = 2024;
अपेक्षित आउटपुट:
bool expected = true;इनपुट:
long year = 2024;
अपेक्षित आउटपुट:
bool expected = true;व्याख्या
2024 is divisible by 4 and not by 100.
इनपुट:
year = 2100
अपेक्षित आउटपुट:
expected = Falseइनपुट:
long long year = 2100;
अपेक्षित आउटपुट:
bool expected = false;इनपुट:
long year = 2100;
अपेक्षित आउटपुट:
bool expected = false;व्याख्या
2100 is divisible by 100 but not by 400, so the century exception applies.
कैसे हल करें
पहले खुद कोशिश करें, फिर एक-एक करके संकेत खोलें।
संकेत 1
Most years follow the divisible-by-4 rule, but centuries are exceptions.
संकेत 2
A year divisible by 400 is still a leap year, even though it is also divisible by 100.
संकेत 3
Check the exception before rejecting century years, or you may misclassify years like 2000.
