Palindrome String Check

Given an alphabetical string S, determine whether it is a palindrome. A palindrome is a string that reads the same backward as forward.

Input:

The first line contains an integer T, the number of test cases.
Each of the following T lines contains a single alphabetical string S.

Output:

For each test case, output 1 if the string S is a palindrome, otherwise output 0. Print the result for each test case on a new line.

Example:

Input:
T = 1
S = "racecar"
Output:
1
Explanation:

The string S = "racecar" is the same when reversed. Therefore, it is a palindrome and the output is 1.

Constraints:

  • 1 ≤ T ≤ 1000
  • 1 ≤ |S| ≤ 105
  • S consists of only lowercase English alphabets.
  • The sum of lengths of all test cases Σ|S| ≤ 2 * 106
  • Time limit: 1 second
