In the toy factory, the elves are programming a digital clock to keep them on schedule with gift production. However, they have encountered an interesting programming challenge. They need a function that, given a time in 'HH:MM' format, creates a visual representation of this time on a digital clock by returning an array of arrays of characters.
The clock screen has 7 rows and 17 columns, and each digit of the time takes up 7 rows and 3 columns. The digits are composed of asterisks (*) and blank spaces (). There is an empty column between each digit.
The colon separating hours and minutes is drawn using two asterisks (*) and is always placed in the same position, in rows 2 and 4, in column 9, respectively (note: row and column indexing starts at 0).
For example, if the function receives 01:30, it should return:
drawClock('01:30') // ⬇️

]To know how to draw each digit, we have been given the following image. As you can see, each digit is composed of 7 rows and 3 columns.
