The input string "Java Program" is defined, and we convert it into a character array. Using a for loop, each character is pushed onto the stack. As the stack follows LIFO, popping elements from it will yield the characters in reverse order, which are stored in a new character array. ...

Let’s consider a simple example where we have an array of integers and we want to print them in reverse order using aforloop. publicclassReverseTraversal{publicstaticvoidmain(String[]args){int[]numbers={1,2,3,4,5};for(inti=numbers.length-1;i>=0;i--){System.out.println(numbers[i])...
Program 2: Reverse a number using for Loop The logic in this program is same as above program, here we are usingfor loopinstead of while loop. As you can see, in this program we have not used the initialization andincrement/decrementsection of for loop because we have already initialized ...
Reverse a String With the for Loop in C# The for loop iterates through a specific section of code for a fixed amount of times in C#. We can use a for loop to reverse the contents of a string variable. See the below example code. using System; namespace reverse_string { class Program...
One solution to the above problem is to use an inbuilt string class of java that is mutable i.e. StringBuilder, which cuts/appends the string in O(1) time. Therefore, java code usingStringBuilderclass with time complexity O(n) is as follows: ...
String[] array = {"A", "B", "C", "D", "E"}; ArrayUtils.reverse(arr); System.out.println(Arrays.toString(arr)); //[E, D, C, B, A] 5. Conclusion In this short tutorial, we learned to reverse an array using different techniques. We learned to use for-loop, swapping items,...
First, the length of the whole string is assigned to the variable len, then a container for the reversed string (strReversed) is declared as empty. Then, using a for loop, in which i is initialized as 0 and the iteration limit is the string length less 1, the function charAt() is ...

In natural language processing and parsing, searching for a string from end to start is often simpler. For debugging, a string reverse would be useful, or as an alternative way of writing the loop (reverse the string and then loop from index 0 to n-1). ...
