Insertion Sort

Insertion sort is a very simple sorting algorithm. Insertion sort is an in-place and comparison based algorithm in which an element is compared with its previous adjacent element and sorted. In this algorithm after each iteration we get a partially sorted algorithm.

 Insertion sort works well with small datasets but its efficiency decreases when the size of the dataset increases. It is less efficient that quick sort, merge sort or heap sort but is better that selection and bubble sort.

 It has a worst case time complexity of o(n2), hence is less efficient for large datasets.

Hashing with Quadratic Probing

Hashing is a technique used for storing , searching and removing elements in almost constant time. Hashing is done with help of a hash function that generates index for a given input, then this index can be used to search the elements, store an element, or remove that element from that index. A hash function is a function that is used to map the data elements to their position in the data structure used. For example if we use an array to store the integer elements then the hash function will generate position for each element so that searching, storing and removing operation on the array can be done in constant time that is independent of the number of elements in the array. For better look at the example below. now we face a problem if for 2 numbers same position is generated example consider elements 1 and 14 1 % 13 = 1 14 % 13 = 1 so when we get 1 we store it at the first position, but when we get 14 we see that the position 1 is already taken, this is a case of colli...
