Question
The question in the image below is a C++
![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;
unsigned long long int sum;
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
sum = sum + j;
1; j <= n; j++)
What us 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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F620c60a1-10fe-416e-8b85-1e75a34b227e%2F3ea39446-a712-4e13-9ad5-61af2ad1e457%2Fia13717_processed.png&w=3840&q=75)
