How To Reverse The String?

Use a loop to read the string from the last character to the first

Store each character in reverse order

Use built-in reverse functions if the language provides them

Convert the string to an array or list of characters before reversing

Join the reversed characters back into a string

For recursive reversal, reverse the substring after the first character and append the first character at the end

For in-place reversal on mutable character arrays, swap characters from both ends moving toward the center
