Condense Whitespace

Problem Description​

Write a function that returns a string with any consecutive spaces replaced with a single space. The function removeExtraSpaces should remove extra spaces between characters in a string, keeping only one space where multiple spaces were present.

Input​

  • A single string.

Output​

  • A string with any consecutive spaces replaced with a single space.

Constraints​

  • The input string may contain any number of spaces, including leading, trailing, and multiple consecutive spaces between words.

Example​

Input:

"a   b   c"

Output:

"a b c"

Explanation:
The input string has multiple consecutive spaces between 'a', 'b', and 'c'. These are replaced with single spaces.

Input:

"    a"

Output:

" a"

Explanation:
The input string has leading spaces which are condensed to a single space before 'a'.

Input:

"abc"

Output:

"abc"

Explanation:
The input string has no extra spaces, so it remains unchanged.
