Remove Vowels

Given a string S containing lowercase letters and spaces, your task is to remove all vowels from the string while maintaining the order of the remaining characters.

The vowels to be removed are \(a, e, i, o, u\). For example, if S = "hello world", the output should be "hll wrld".

This problem tests simple string manipulation and is suitable for beginners in competitive programming.
