Reverse the String Problem Statement

You are given a string STR which contains alphabets, numbers, and special characters. Your task is to reverse the string.

Example:

Input:

STR = "abcde"

Output:

"edcba"

Input:

The first line of input contains a single integer 'T', representing the number of test cases.

Each test case consists of one line containing the string 'STR'.

Output:

For each test case, output the reversed string of 'STR'. Each result must be printed on a new line.

Example:

Input: 2 hello world!

Output: olleh !dlrow

Constraints:

1 ≤ T ≤ 10

1 ≤ |STR| ≤ 10^5, where |STR| is the length of the string STR.

Time limit: 1 second.

Note:

Just implement the function; you do not need to print anything.

Accepted Answer

Reverse a given string containing alphabets, numbers, and special characters.

Iterate through the string from the end to the beginning and append each character to a new string.
Use built-in functions like reverse() or StringBuilder in languages like Python or Java for efficient reversal.
Handle special characters and numbers while reversing the string.
Ensure to consider the constraints on the length of the string and the number of test cases.

Accepted Answer

s = "hello"
reversed_s = s[::-1]
print(reversed_s)  
# Output: "olleh"

built-in functions-

s = "hello"
reversed_s = ''.join(reversed(s))
print(reversed_s)  # Output: "olleh"
