{ "data": { "question": { "questionId": "2727", "questionFrontendId": "2678", "boundTopicId": null, "title": "Number of Senior Citizens", "titleSlug": "number-of-senior-citizens", "content": "

You are given a 0-indexed array of strings details. Each element of details provides information about a given passenger compressed into a string of length 15. The system is such that:

\n\n\n\n

Return the number of passengers who are strictly more than 60 years old.

\n\n

 

\n

Example 1:

\n\n
\nInput: details = ["7868190130M7522","5303914400F9211","9273338290F4010"]\nOutput: 2\nExplanation: The passengers at indices 0, 1, and 2 have ages 75, 92, and 40. Thus, there are 2 people who are over 60 years old.\n
\n\n

Example 2:

\n\n
\nInput: details = ["1313579440F2036","2921522980M5644"]\nOutput: 0\nExplanation: None of the passengers are older than 60.\n
