Reverse a string
Program to reverse a string (Iterative and Recursive) - GeeksforGeeks
Here are the list of programs on reversing of a string entered by user at run-time:. Then reverse it and print the reversed string as shown in the program given below:. Here is its answer:. Now supply the string say this is codescracker as input and press ENTER key to reverse it and print its reverse as shown in the snapshot given below:. That is, if string say this is codescracker entered by user, then it gets stored in str in a way that:. Now because, the initial value of i is 0, therefore the condition of while loop str[i]!
Tisha Richardson, 18, Washington, Missouri. I am delighted to have new essays and I will definitely be using their services again. I can recommend them most highly to anyone who requires a professional proofreader. Thanks again.
The fastest and easiest? In this particular example, the slice statement  means start at the end of the string and end at position 0, move with the step -1 , negative one, which means one step backwards. Now we have a string txt that reads "Hello World" backwards. If you like to have a function where you can send your strings, and return them backwards, you can create a function and insert the code from the example above.
Since recently setting up a forum for Three Devs and a Maybe , we have started to partake in a weekly code-kata. In this case the language is PHP, and below are some of the many ways contrived to solve the problem. The most imperative approach to reverse a string is by looping over each character with indexes at each end, swapping their contents upon each iteration.
