PROGRAMMING PROBLEMSFor the following programming problems, you need to time a section of code in C++. For example, thefollowing statements time the execution of the function doSomething:#include clock_t start = clock();doSomething();clock_t finish = clock();double overallTime = static_cast (finish start) / CLOCKS_PER_SEC; ³1. Consider the following two loops:// Loop Afor (i = 1; i <= n; i++)for (j = 1; j <= 10000; j++)sum = sum + j;// Loop Bfor (i = 1; i <= n; i++)for (j = 1; j<= n; j++)sum = sum + j;What is the Big O of each loop? Design and implement an experiment to find a value of n for which Loop B isfaster than Loop A.2. Repeat the previous project, but use the following for Loop B:// Loop Bfor (i = 1; i <= n; i++)for (j = 1; j

Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

PROGRAMMING PROBLEMS
For the following programming problems, you need to time a section of code in C++. For example, the
following statements time the execution of the function doSomething:
#include <ctime>
clock_t start = clock();
doSomething();
clock_t finish = clock();
double overallTime = static_cast<double> (finish start) / CLOCKS_PER_SEC; ³
1. Consider the following two loops:
// Loop A
for (i = 1; i <= n; i++)
for (j = 1; j <= 10000; j++)
sum = sum + j;
// Loop B
for (i = 1; i <= n; i++)
for (j = 1; j<= n; j++)
sum = sum + j;
What is the Big O of each loop? Design and implement an experiment to find a value of n for which Loop B is
faster than Loop A.
2. Repeat the previous project, but use the following for Loop B:
// Loop B
for (i = 1; i <= n; i++)
for (j = 1; j<n; j++)
for (k = 1; k <= j; k++)
sum sum + k;
