Recursive Way to reverse a string

1. Calculate the length (Len) of string.
2. Initialize the indexes of the array. Start = 0, End = Len-1.
3. swap the value of pszData[Start] with pszData[End].
4. Change the indexes’ of an array as below and Recursively call reverse function for the rest array. Start = start +1; End = end – 1.

How to reverse the digits of an integer in JavaScript?

Write a program to reverse the digits of an integer. Time Complexity: O (log (n)), where n is the input number. Time Complexity: O (log (n)) where n is the input number. We will convert the number to a string using StringBuffer after this, we will reverse that string using the reverse () method

We will convert the number to a string using StringBuffer after this, we will reverse that string using the reverse () method So for the above input if we try to solve this by reversing the string, then the output will be 00123.

How to reverse a string in ECMAScript 6?

First, use Array.from () to turn a string into an array, then Array.prototype.reverse () to reverse the array, and then Array.prototype.join () to make it back a string. In ECMAScript 6, you can reverse a string even faster without using .split (”) split method, with the spread operator like so: Seems like I’m 3 years late to the party…
