Word Presence in Sentence

Determine if a given word 'W' is present in the sentence 'S' as a complete word. The word should not merely be a substring of another word.

Input:

The first line contains an integer 'T', the number of test cases.
The first line of each test case contains the sentence 'S'.
The second line of each test case contains the word 'W'.

Output:

For each test case, output "Yes" if the word 'W' is present in the sentence 'S' as a complete word; otherwise, output "No".
Each output should be printed on a new line.

Example:

Input:

T = 1
S = "hello world"
W = "hello"

Output:

Yes

Constraints:

• 1 ≤ T ≤ 50
• 1 ≤ |S|, |W| ≤ 10000
• 'S' and 'W' comprise lowercase letters only

Note: Words are separated by spaces in sentence 'S'.
