First of all, we input the string that we would like to reverse as a stringbuilder.

Now, we run a for loop till half the length of the string and inside it, set the int front as the last index - i which is sb.lenght() - 1 -i.

Now set the char frontchar as sb.CharAt(front) and the backchar as sb.CharAt(back). Then we use the sb.setcharat(front, backchar) to replace the char at the front with the char at the back and do the same with backchar.

That's it for my first blog. Thank You.
