Insertion Sort Best Case Analysis
The best case input is an array that is already sorted.
In this case insertion sort has a linear running time (i.e., Θ(n)).
During each iteration, the first remaining element of the input is only compared with the right-most element of the sorted subsection of the array
Given Input: [5 6 7 8 9 ]
- Item=6 > data[0]=1. while condition is false and data[1] is assigned with item=6.
Number of Comparison= 1 - Item=7 > data[1]=1.
while condition become false and data[2] is
assigned with item=7.
Number of Comparison is 1 - Item=8 > data[2]=7.
while condition become false and data[3] is assigned with item=8.
Number of Comparison is 1 - Item=9 > data[3]=8. while condition become false and data[4] is assigned with item=9.
Number of Comparison is 1
Best Case Analysis
****************
There are 4 passes to sort array with elements.
In each pass there is only 1 comparison.
Example,
Pass 1, 1 comparison
Pass 2, 1 comparison
Pass 3, 1 comparison
Pass 4, 1 comparison
In this example, the total comparisons for an array with size 5
is 4. Therefore, for best case, the number of comparison is n-
1 which gives linear time complexity linear O(n).

quick SORT
The efficeieny of the quicksort depends on the pivot element. However the pivot element can also be choosen at random order or from the last element of the array
