Character Frequency Counter

You are given a string which may contain letters, digits, spaces, and special characters. Your task is to count the frequency of each character in the string in a case-sensitive manner. The order of output should be the order in which each distinct character appears in the input.

For example, if the input is "hello", you should output:

h: 1
e: 1
l: 2
o: 1

If the input is an empty string, print nothing.

Note: The input will be taken from stdin and the result should be printed to stdout.

inputFormat

The input consists of a single line containing the string.

The string may include spaces and special characters.

outputFormat

For each distinct character in the input string (in the order of their first occurrence), print a line in the format:

character: count

If the string is empty, output nothing.

## sample

hello

h: 1
e: 1
l: 2
o: 1
