Inserting Elements in an Array - Array Operations Last Updated : 07 Nov, 2024 Comments Improve Suggest changes Like Article Like Report In this post, we will look into insertion operation in an Array, i.e., how to insert into an Array, such as:Insert Element at the Beginning of an ArrayInsert Element at a given position in an ArrayInsert Element at the End of an ArrayInsert Element at the Beginning of an ArrayInserting an element at the beginning of an array involves shifting all existing elements one position to the right to create an empty space for the new element at index 0.Examples:Input: arr[] = [10, 20, 30, 40], ele = 50Output: [50, 10, 20, 30, 40]Input: arr[] = [], ele = 20Output: [20]To know more about the implementation, please refer Insert Element at the Beginning of an Array.Insert Element at a given position in an ArrayInserting an element at a given position in an array involves shifting the elements from the specified position onward one index to the right to make an empty space for the new element. This operation ensures that the order of the existing elements is preserved while placing the new element at the desired index. After shifting the elements, the new element is inserted at the target position.Examples:Input: arr[] = [10, 20, 30, 40], pos = 2, ele = 50Output: [10, 50, 20, 30, 40]Input: arr[] = [], pos = 1, ele = 20Output: [20]Input: arr[] = [10, 20, 30, 40], pos = 5, ele = 50Output: [10, 20, 30, 40, 50]To know more about the implementation, please refer Insert Element at a Given Position in an Array.Insert Element at the End of an ArrayInserting an element at the end of an array involves adding the new element to the last available index of the array. Inserting an element at the end of the array takes constant time provided there is enough space in the array to add the new element.Examples:Input: arr[] = [10, 20, 30, 40], ele = 50Output: [10, 20, 30, 40, 50]Input: arr[] = [], ele = 20Output: [20]To know more about the implementation, please refer Insert Element at the End of an Array.Related Posts: Searching Elements in an Array - Array OperationsDeleting Elements in an Array - Array Operations Comment More infoAdvertise with us Next Article Inserting Elements in an Array - Array Operations C code_r Follow Improve Article Tags : DSA Similar Reads DSA Tutorial - Learn Data Structures and Algorithms DSA (Data Structures and Algorithms) is the study of organizing data efficiently using data structures like arrays, stacks, and trees, paired with step-by-step procedures (or algorithms) to solve problems effectively.

Non-Linear Components are those that are changed with respect to the voltage and current. Elements that do not follow ohm's law are called Non-linear Components.

It works on the principle of divide and conquer, breaking down the problem into s 12 min read Merge Sort - Data Structure and Algorithms Tutorials Merge sort is a popular sorting algorithm known for its efficiency and stability. It follows the divide-and-conquer approach. It works by recursively dividing the input array into two halves, recursively sorting the two halves and finally merging them back together to obtain the sorted array. Merge 14 min read Bubble Sort Algorithm Bubble Sort is the simplest sorting algorithm that works by repeatedly swapping the adjacent elements if they are in the wrong order. This algorithm is not suitable for large data sets as its average and worst-case time complexity are quite high.We sort the array using multiple passes.

Perform a Breadth First Search (BFS) traversal starting from vertex 0, visiting vertices from left to right according to the adjacency list, and return a list conta 15+ min read Binary Search Algorithm - Iterative and Recursive Implementation Binary Search Algorithm is a searching algorithm used in a sorted array by repeatedly dividing the search interval in half. The idea of binary search is to use the information that the array is sorted and reduce the time complexity to O(log N).

It is like sorting playing cards in your hands. You split the cards into two groups: the sorted cards and the unsorted cards.
