Explanation:

When you delete white spaces from a string, all of the space characters—such as tabs, spaces, and so on—are eliminated, leaving only the non-whitespace letters.

Algorithm:

  1. Start with an empty result string.
  2. Loop through each character of the input string.
  3. If the character is not a whitespace (‘ ‘), append it to the result.
  4. Return the final result string without white spaces.
