Reverse a String Problem Statement

Given a string STR containing characters from [a-z], [A-Z], [0-9], and special characters, determine the reverse of the string.

Input:

The input starts with a single integer 'T', which represents the number of test cases. Each of the following 'T' lines contains a single string 'STR'.

Output:

For each test case, output a single line containing the reversed string 'STR'. Each result should be printed on a separate line.

Example:

Input: 2 abcde 12345 Output: edcba 54321

Constraints:

1 ≤ T ≤ 10

1 ≤ |STR| ≤ 10^5

Note:

You only need to implement the function to return the expected result; printing it is already taken care of.

Accepted Answer

Reverse a given string containing characters from [a-z], [A-Z], [0-9], and special characters.

Iterate through the characters of the string from end to start and append them to a new string to get the reversed string.
Use built-in functions like reverse() or StringBuilder in languages like Python or Java for efficient reversal.
Ensure to handle special characters and numbers while reversing the string.
Consider edge cases like empty string or strings with only one character.

String str="aB1!cD2@";
		char[] strArr=str.toCharArray();
		int left=0;
		int right=strArr.length-1;
		while (left<right) {
			char temp=strArr[left];
			strArr[left]=strArr[right];
			strArr[right]=temp;
			left++;
			right--;
		}
		String newstr=new String(strArr);
		System.out.println(newstr);
