SG · Answer

How about this:
for(int index = 0; index < input.length() ; index++ ) {
             output.insert(0, input.charAt(index));
            }

Nitesh · Answer

// Converted the String into Char array
		char[] a = str.toCharArray();
		// create a new String
		StringBuilder sb = new StringBuilder();
		// Started a loop
		for (int i = a.length - 1; i >= 0; i--) {
			// Add character
			sb.append(a[i]);
		}
		// Print out the string
		System.out.println(sb);

Using Python :

def reverse(string):
    L = []
    count = 1
    for i in range(0,len(string)):
        L.append(string[len(string)-count])
        count += 1
    L_reverse = ''.join(L)
    return L_reverse
