Exact analysis of insertion sort:
Let us assume the following pseudocode to analyse the exact runtime complexity of insertion sort.
Tj is the time taken to execute the statement through jth iteration.
The statement at line 4 will execute Tj number of times.
The statements at lines 5 & 6 will execute Tj - 1 number of times (one step less) each
Line 7 will execute for (n-1) times
Thus, total time is the sum of time taken for every line multiplied through their cost factor.
Three cases can emerge based on the initial configuration of the input list. First case is where the list was sorted already; second case is the case in which the list is sorted in reverse order and third case is the case where in the list is in random order (unsorted). The best case scenario will emerge while the list is sorted already.
In this unit, we will describe a data structure called Graph. Actually, graph is a general tree along no parent-child relationship. In computer science, Graphs have several applica

1. Write a pseudocode algorithm to print the numbers from 1 to 10, and then from 10 to 1, using exactly one loop. 2. The function contains() takes a food as an argument and tell
Explain principle of Optimality It indicates that an optimal solution to any instance of an optimization problem is composed of optimal solutions to its subinstances.
#question. merging 4 sorted files containing 50,10,25,15 records will take time?
B Tree Unlike a binary-tree, every node of a B-tree may have a variable number of keys and children. The keys are stored in non-decreasing order. Every key has an associated ch
In internal sorting, all of the data to be sorted is obtainable in the high speed main memory of the computer. We will learn the methods of internal sorting which are following:
For a queue a physical analogy is a line at booking counter. At booking counter, customers go to the rear (end) of the line & customers are attended to several services from the fr
Q. Which are the two standard ways of traversing a graph? Explain them with an example of each. Ans: T he two ways of traversing a graph are written below
