Colon-Separated List Formatter

You are given a list of integers. Your task is to convert the list into a single colon-separated string.

For example, if the input is 34 -2 78 14, then the output should be 34:-2:78:14.

The input will be provided via standard input with the integers separated by whitespace, and you should output the result to standard output.

Hint: Consider reading all input numbers and then joining them by colons.
