Answer:
Running RECURSIVE-MATRIX-CHAIN is asymptotically more efficient than enumerating all the ways of parenthesizing the product and computing the number of multiplications of each.
the running time complexity of enumerating all the ways of parenthesizing the product is n*P(n) while in case of RECURSIVE-MATRIX-CHAIN, all the internal nodes are run on all the internal nodes of the tree and it will also create overhead.
Explanation:
When a user is created in Linux using the useradd command, the <em>immediate state</em> of the created account is locked.
- The useradd command can be invoked in other to create a new user account using the following command
sudo useradd fast_user
<em>#fast_user</em><em> </em><em>is</em><em> </em><em>the</em><em> </em><em>name</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>account</em><em> </em><em>created</em><em> </em>
- At this point, the account has been created but it will be locked until the required login details are set. This can be achieved using the line ;
sudo passwd fast_user
Therefore, an account created using the useradd command is in a locked state.

Answer:
#include <iostream>
#include <vector>
using namespace std;
void calGPA();
vector<int> g;
vector<int> h;
int main(){
char pushMore = 'y';
int fg, fh;
for (;;){
if (pushMore == 'n'){
break;
} else{
cout<< "Enter integer for grade: ";
cin>> fg;
cout<< "Enter integer for credit hours: ";
cin>> fh;
g.push_back(fg);
h.push_back(fh);
cout<< "Do you want to add more grade and credit hours? y/n: ";
cin>> pushMore;
}
}
calGPA();
}
void calGPA(){
double total = 0, GPA;
for (int i = 0; i < g.size(); ++i) {
total += g.at(i) * h.at(i) ;
}
cout<< "The GPA is : "<< total/g.size();
}
Explanation:
The C++ source code above defines two vectors 'g' and 'h'. The latter holds the grades of a student while the former holds the credit hours for the subject taken. The void 'calGPA' function calculates and prints the student's GPA.
