C Program For Insertion Sort Algorithm in Data Structure
Learn How To Sort Integer Arrays using Insertion Sort Algorithm in C Programming Language. It is important that we should know about How A For Loop Works before getting further with the C Program Code. The insertion sort technique is very simple to implement and is efficient when the number of elements to be sorted are less.
What is Insertion Sort Algorithm?
In this algorithm, every Element is Inserted at a proper place in a Sorted List. It is the same technique used while playing Cards. The Array is considered to be divided into two parts.
Initially, the Sorted part contains only the first element of the list and Unsorted part contains the remaining elements. In every pass, the first element from the Unsorted part is taken and inserted into the Sorted part at appropriate places. For n elements in the list, the list gets Sorted after n – 1 passes.
Insertion Sort Algorithm Analysis
Insertion Sort is a Stable Sort. Since it requires only one Temporary variable, it is an In-Place Sort. Space Complexity is O(1). The best case scenario would fetch run time complexity of O(n) when the data is already in sorted order. The worst case is when the data is in reverse order which will be having a run time complexity of O(n2).
