Character Formation Check
Determine if the second string STR2
can be constructed using characters from the first string STR1
. Both strings may include any characters.
Input:
The first line contains an integer T
, the number of test cases.
For each test case:
The first line contains the string STR1
.
The second line contains the string STR2
.
Output:
For each test case, return "YES"
if STR2
can be formed from the characters of STR1
, otherwise return "NO"
.
Example:
Input:
STR1 = "codingninjas", STR2 = "sing"
Output:
"YES"
Explanation:
The second string, "sing", can be formed using characters "s", "i", "n", "g" from the first string "codingninjas".
Constraints:
1 ≤ T ≤ 100
1 ≤ |STR1|, |STR2| ≤ 1000
- Time Limit: 1 sec
Note:
There's no need to print the output. Implement the function that returns the expected results.
