The assignment for the Kuvempu University for the BSc-IT 4th semester on Algorithm has been provided below:

1.
___________ is the process of executing a correct program on data sets and measuring the time and space it takes tocompute the results?
Ans. Profiling2.

Define algorithm? What are its properties?
Ans.
An algorithm is a set of instructions that provide step-by-step specifications to perform a task.The properties of an algorithm are:
Input
: Specifies the data set that is applied to the algorithm to check its validity.
Output
: Specifies the data set that is produced as a result of the algorithm execution.
Definiteness
: Specifies that the instructions described in the algorithm should be welldefined and should not create any ambiguity.
Termination
: Specifies that the instructions described in the algorithm must contain aproper termination condition.
Effectiveness
: Specifies that the algorithm take less time and less memory space duringits execution.
3.
What is debugging and what is profiling?
Ans.
Debugging is the process of identifying and fixing the errors in a program. Errors in a program can be identified byexecuting the program with a sample dataset.Profiling is the process of measuring the performance of the program by executing it on different data sets. Performanceof a program is measured by recording the time and memory space that the program takes during its execution.
4.
One of the properties of an algorithm is beauty (true/false)
Ans. FalseSolutions to Chapter Two Questions1.

Give at least 5 real life examples where we use stack operations.
Ans.
The real life examples of stacks are:

Bangles in a hand
: The bangles wore in a hand follow last-in-first-out (LIFO) strategy of stack. The bangle that you wear first is the last one to be taken out while removing all thebangles from the hand. The bangle that is worn last is the first one to be taken out.
Same circumference circular rings in a pole
: The rings having same circumference placed into a pole also follow LIFO strategy. The topmost ring, which was the last to be placed in the pole, is the first one to be taken out.
Sacks full of wheat placed one over other
: The sack at the top is removed first and the sack at the bottom is removed last.
The bolts screwed to a single nut
: When the bolts are screwed to a single nut, the last screwed bolt is unscrewed first and the bolt that was screwed first is unscrewed in the last.
Battery cells in a torch
: The battery cells in a torch also follow the same LIFO strategy of stack.
