Reverse An Array - C Program

About Reverse An

Time Complexity On, Copying elements to a new array is a linear operation. Auxiliary Space On, as we are using an extra array to store the reversed array. Expected Approach - 1 Using Two Pointers - On Time and O1 Space. The idea is to maintain two pointers left and right, such that left points at the beginning of the array and right points to the end of the array.

reversearray_name, array_name size function exits in algorithm.h header file. 3.Now print the array. N.B Here we use new and delete for dynamic memory allocation.

Summary In this tutorial, we will learn different ways to reverse an array in C programming language. Example Array 5, 6, 2, 3 Reverse 3, 2, 6, 5 There are multiple ways to reverse an array in C. Let's discuss each of them. Method 1 Using an Extra Array

The reverse of an array means to change the order of the given array's elements. This technique reverses the last element of the array into the first one, and the first element becomes the last. However, the process continues until all characters or elements of the array are completely reversed.

Download Run Code. 3. Using Stack. Another plausible way of reversing an array is to use the stack data structure.The idea is to push each array element into a stack. Then pop values from the stack one by one and assign each popped item back to the original array starting from the beginning.

In this example, we include the ltalgorithmgt header to access the stdreverse function. We call reverse with two parameters the beginning and the end of the array. This function handles the swapping internally, making the code cleaner and easier to read. The result is the same as the previous method, but with less code to manage.

Reverse an Array in C. This program reverses an array before printing. When the array gets reversed, then when you print the same array, it shows its elements in reverse order. This program also allows the user to define the size of the array. To reverse an array in C programming, you have to ask the user to enter the array's size and then

Method 1 Printing array in reverse order. Method 2 In-place reversing of the original array Method 3 Recursive in-place reversing of the original array Method 4 Using inbuilt function Method 1 Simple Printing Array in Reverse Objective Reverse array in C. Run a loop in reverse order i.e, from index n-1 to index 0. Print i-th element

Single-dimensional Arrays These are the most common arrays, holding a linear sequence of elements. For example, an array of integers can be created to store student grades. Multi-dimensional Arrays These arrays extend the concept of a single array by allowing indexes to reference multiple levels of data, like a matrix in mathematics. An

Algorithm to reverse elements of a given array in C. Let A be array to be reversed with n number of elements. Define two indexes i and j pointing first and last element of an arrayi0, jn-1. Repeat the loop for n2 number of times. In each iteration, swap the array elements pointed by pointer i and j. After swapping modifies indexes as i
