Character Count in String
Write a program that counts the frequency of each character in the input string. The output should be in the format 'character: count', with each character frequency printed on a new line. Ignore spaces and print only characters that appear in the string.
Example:
Input:
hello world
Output:
h: 1
l: 3
o: 2
r: 1
w: 1
d: 1
