Task $1$: Write C$++$ program that $$ Declares an array of size $1000$ and populates it with random numbers between $1$ and $100.$ Then it finds factorial of these numbers and checks how many of these prime numbers are. Also find the time taken by the system to perform these tasks. $$ Now, create two thread such that the first thread process finds the factorial of these numbers $($given in the above array$)$ while the other finds how many of these are prime. Now, calculate the time taken by these children processes to perform these tasks. $$ Now, compare which approach performs bette
