Reverse Words In A String Problem Statement

Given a string of length N, reverse the string word by word. Ensure that the output reversed string has a single space between two words and does not contain leading or trailing spaces.

Example:

Input:

" Welcome to Coding Ninjas"

Output:

"Ninjas Coding to Welcome"

Explanation:

The reversed string contains only a single space between words and eliminates any leading or trailing spaces.

Input:

The first line of input contains an integer T, representing the number of test cases. Each of the following T lines contains a string to be reversed word by word.

Output:

For each test case, return the reversed string with a single space between words and no trailing spaces.

Constraints:

Example:

Input:

"  Welcome to   Coding  Ninjas"

Output:

"Ninjas Coding to Welcome"

Explanation:

The reversed string contains only a single space between words and eliminates any leading or trailing spaces.

Input:

The first line of input contains an integer T, representing the number of test cases. Each of the following T lines contains a string to be reversed word by word.

Output:

For each test case, return the reversed string with a single space between words and no trailing spaces.

Constraints:

1 <= T <= 50
0 <= N <= 10^5

Time Limit: 1 second

Accepted Answer

Reverse the words in a string while ensuring single spaces and no leading or trailing spaces.

Input Handling: Read multiple test cases, each containing a string to be reversed word by word.
Trimming Spaces: Use string manipulation to remove leading and trailing spaces before processing.
Splitting Words: Split the string into words based on spaces, ensuring to handle multiple spaces correctly.
Reversing Words: Reverse the order of the words in the list obtained from the split operation.
Joining Words: Join the reversed list of words with a single space to form the final output string.
