Practice/Netflix/Timer Function

Timer Function

CodingMust

Problem Overview

Implement a function that converts seconds into a human-readable time format showing months, weeks, days, hours, minutes, and seconds. This is similar to how Netflix might display content duration or time remaining.

The function must be implemented recursively and follow specific formatting rules.

Time Unit Conversions

• 1 minute = 60 seconds
• 1 hour = 60 minutes = 3,600 seconds
• 1 day = 24 hours = 86,400 seconds
• 1 week = 7 days = 604,800 seconds
• 1 month = 30 days = 2,592,000 seconds

Formatting Rules

1. Don't show zero units except for seconds

   • Good: "5 minutes, 0 seconds"
   • Good: "2 days, 3 minutes, 10 seconds"
   • Bad: "2 days, 0 hours, 3 minutes, 10 seconds"

2. Always show seconds even if zero (except when larger units exist that equal exactly 0 seconds)

3. Use singular form for unit names regardless of count

   • Use "1 minutes" not "1 minute"
   • Use "3 hours" not "3 hour"

4. Separate units with commas and spaces: "X units, Y units"

Example

` timer(55)

Returns "55 seconds"

timer(65)

Returns "1 minutes, 5 seconds"

65 = 1*60 + 5

timer(3805000)

Returns "1 months, 2 weeks, 56 minutes, 40 seconds"

3805000 = 12592000 + 2604800 + 086400 + 03600 + 56*60 + 40

Zero days and hours are omitted

timer(3600)

Returns "1 hours, 0 seconds"

Exactly 1 hour, show 0 seconds but omit 0 minutes

`

Requirements

• Must be implemented recursively (no loops)
• Cannot use standard date/time libraries
• Handle all edge cases correctly
• Format output exactly as specified

Constraints

• 0 <= seconds <= 10^9
