You are encouraged to solve this task according to the task description, using any language you may know.
- Task
Write a function or program which:
- takes a positive integer representing a duration in seconds as input (e.g.,
100), and - returns a string which shows the same duration decomposed into weeks, days, hours, minutes, and seconds as detailed below (e.g., "
1 min, 40 sec").
Demonstrate that it passes the following three test-cases:
Test Cases
| input number | output string |
|---|---|
| 7259 | 2 hr, 59 sec
|
| 86400 | 1 d
|
| 6000000 | 9 wk, 6 d, 10 hr, 40 min
|
Details
- The following five units should be used:
unit suffix used in output conversion week wk1 week = 7 days day d1 day = 24 hours hour hr1 hour = 60 minutes minute min1 minutes = 60 seconds second sec - However, only include quantities with non-zero values in the output (e.g., return "
1 d" and not "0 wk, 1 d, 0 hr, 0 min, 0 sec"). - Give larger units precedence over smaller ones as much as possible (e.g., return
2 min, 10 secand not1 min, 70 secor130 sec) - Mimic the formatting shown in the test-cases (quantities sorted from largest unit to smallest and separated by comma+space; value and unit of each quantity separated by space).
Ada

Fortran
If the PARAMETER statements were replaced (say with suitable DATA statements) then this could be compiled with Fortran 77, if a find-last-non-blank function were to be supplied and a supplementary scratchpad used so that the numbers could be placed without leading spaces (thus "9" and "10", not " 9") because the I0 format specifier is a F90 facility. Earlier Fortran compilers lacking a CHARACTER variable would present further difficulty.
If the time to describe was not an integer but a floating-point value with fractional parts, then there is a complication. The number of seconds can be less than sixty, but, on output, 60 seconds can appear. If the number of seconds was to be written with one decimal digit (say) and the output format was F4.1 for that, then if the value was 59·95 or more, it will be rounded up for output, in this example to 60·0. Various systems make this mistake, as also with latitude and longitude, and it is a general problem. A fixup pass is necessary before generating the output: maintain an array with the integer values of the various units, then (for one decimal digit usage) check that the seconds part is less than 59·95. If not, set it to zero and augment the minutes count. If this is 60 or more, set it to zero and augment the hours count, and so on. Thus the array. <lang Fortran>

Rust
This solution deviates from the prompt a bit in order to make it more general. The benefit of doing it this way is that any values can be filled in for days, hours, minutes and seconds and the `balance` method will do the balancing accordingly. Also, rather than converting the value into a String, it simply implements the `Display` trait. <lang rust>use std::fmt;
struct CompoundTime {
w: usize, d: usize, h: usize, m: usize, s: usize,
}
macro_rules! reduce {
($s: ident, $(($from: ident, $to: ident, $factor: expr)),+) => {{
$(
$s.$to += $s.$from / $factor;
$s.$from %= $factor;
)+
}}
}
impl CompoundTime {
#[inline]
fn new(w: usize, d: usize, h: usize, m: usize, s: usize) -> Self{
CompoundTime { w: w, d: d, h: h, m: m, s: s, }
}
#[inline]
fn balance(&mut self) {
reduce!(self, (s, m, 60), (m, h, 60),
(h, d, 24), (d, w, 7));
}
}
impl fmt::Display for CompoundTime {
fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
write!(f, "{}w {}d {}h {}m {}s",
self.w, self.d, self.h, self.m, self.s)
}
}

println!("Before: {}", ct);
