// formatAs12HourClock currently has a 🐛

// a) Write an assertion to check the return value of formatAs12HourClock when it is called with an input "17:42"
// b) Check the assertion output and explain what the bug is // it wasnt returning the minutes and wasnt adding a zero infront of 5
// c) Now fix the bug and re-run all your assertions
