For example, given the number 357 = 17x7x3, you arrange 3 dots in a triangle, 7 versions of those tri...
For any positive 32-bit integer (1 ≤ n ≤ 0xFFFFFFFF) output the number of bits needed to represent that integer.
Test cases
| n | n in binary | bits needed |
|----------------------------------|
| 1 | 1 | 1 |
| 2 | 10 | 2 |
| 3 | 11 | ...
You are to create a program that creates exact clones of itself infinitely until stopped. Whatever is in the original program must be in the clones. In other words, the clones and original program are the same in every way except for that the clones are text files.
Example:
If my original progr...

The challenge is simplistic, given an input time in any one of the following formats:
hh, hh:mm or hh:mm:ss with 0 < hh < 24, 0 < mm < 60, 0 < ss < 60.
Output what time it currently is using the following symbols:
AA LABEL FOR ASCII SYMB ASCII HEXIDEC
