# --description--
|
|
|
|
Given an integer number of seconds, return a string representing the same duration in the format `"H:MM:SS"`, where `"H"` is the number of hours, `"MM"` is the number of minutes, and `"SS"` is the number of seconds. Return the time using the following rules:
|
|
|
|
- Seconds: Should always be two digits.
|
|
- Minutes: Should omit leading zeros when they aren't needed. Use `"0"` if the duration is less than one minute.
|
|
- Hours: Should be included only if they're greater than zero.
|
|
|
|
# --hints--
|
|
|
|
`format(500)` should return `"8:20"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(format(500), "8:20")`)
|
|
}})
|
|
```
|
|
|
|
`format(4000)` should return `"1:06:40"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(format(4000), "1:06:40")`)
|
|
}})
|
|
```
|
|
|
|
`format(1)` should return `"0:01"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(format(1), "0:01")`)
|
|
}})
|
|
```
|
|
|
|
`format(5555)` should return `"1:32:35"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(format(5555), "1:32:35")`)
|
|
}})
|
|
```
|
|
|
|
`format(99999)` should return `"27:46:39"`.
|
|
|
|
```js
|
|
({test: () => { runPython(`
|
|
from unittest import TestCase
|
|
TestCase().assertEqual(format(99999), "27:46:39")`)
|
|
}})
|
