Mar 25, 2025 · Since a stack follows the Last In, First Out (LIFO) principle, popping elements from the stack and storing them back into the array results in a reversed order. This efficiently reverses the array without using extra loops for swapping. Follow the steps given below to reverse an array using stack. Create an empty stack.

Do you want to know how to reverse array using stack? Here you will get code in both programming language c and java.

You are given a stack St. You have to reverse the stack using recursion. Example 1: Input: St = {3,2,1,7,6} Output: {6,7,1,2,3} Explanation: Input stack after reversing will look like the stack in the output. Example 2: Input: St = {4,3,9,6} Output: {6,9,3,4} Explanation: Input stack after reversing will look like the stack in the output. Your ...

Jan 25, 2017 · You are reversing the array twice; that's why you have the original array. How? Take for an example a 10-element array. As your first step, you'll swap 0th and 9th element. As your last step, you'll swap 9th and 0th element. Net result: no …

Nov 20, 2024 · The simplest method to reverse an array in C program is by using two pointers: one starting at the beginning (left) and one at the end (right) of the string. Swap the elements at these pointers while moving them towards centre of the array until the pointers meet.

Learn 5 unique ways to reverse an array in C programming. Explore step-by-step examples, code snippets, and efficient methods to reverse arrays for projects.

Oct 11, 2013 · for loop condition should be 'i < n'. and prototype declaration should match. and "int n" is the size of array. So "i<=n" would make the same array reversed from end to mid, and again from mid to top. So result is same as array. make "n" as half of the array size.

Dec 18, 2022 · In C, there are no inbuilt functions to reverse an array, we have to write the code for it on our own. An array can be reversed using different methods and algorithms - printing it from the last element, using an auxiliary array, recursion, swapping, etc.

Feb 18, 2014 · i want to reverse a sentence using stack in c. eg. how are you => you are how. i have written the following program. char *var; struct rev *next; . int start, j = 0; char *p="Hi, How are you? Hope everything is fine"; char *s; char *t; *t = '\0'; s = p; while(1) { if(*p == ' '|| *p == '\0') { printf("Inside if \n"); *(t + j) = '\0';

Mar 17, 2025 · In C, there is no slicing mechanism. Hence, we need to dive into lower-level solving. 1. Declaring another array. We can declare another array, iterate the original array from backward and send them into the new array from the beginning. 2. Iteration and swapping.
