What is the best case for insertion sort?
So, if every element is greater than or equal to every element to its left, the running time of insertion sort is Θ(n)\Theta, left parenthesis, n, right parenthesis. This situation occurs if the array starts out already sorted, and so an already-sorted array is the best case for insertion sort.
What is first step in insertion sort?
- If it is the first element, it is already sorted.
- Pick the next element.
- Compare with all the elements in sorted sub-list.
- Shift all the the elements in sorted sub-list that is greater than the value to be sorted.
- Insert the value.
- Repeat until list is sorted.
Why do we use insertion sort?
This algorithm is one of the simplest algorithm with simple implementation. Basically, Insertion sort is efficient for small data values. Insertion sort is adaptive in nature, i.e. it is appropriate for data sets which are already partially sorted.
Which is better insertion or selection sort?
Insertion sort runs much more efficiently if the array is already sorted or “close to sorted.” Selection sort always performs O(n) swaps, while insertion sort performs O(n2) swaps in the average and worst case. Selection sort is preferable if writing to memory is significantly more expensive than reading.
What is sorted list?
A sorted list is a combination of an array and a hash table. It contains a list of items that can be accessed using a key or an index.
