Consider this binary search tree:______.
Nitella [24]

Answer:

The new root will be 2.

<em></em>

Explanation:

The binary tree is not properly presented (See attachment)

To answer this; first, we need to order the nodes of the tree in a pre-order traversal.

We use pre-order because the question says if something is removed from the left child.

So, the nodes in pre-order form is: 14, 2, 1, 5, 4, 16.

The root of the binary tree is 14 and if 14 is removed, the next is 2.

<em>Hence, the new root will be 2.</em>

Resource:

This question has already been answered here: brainly.com/question/18415952

Explanation:

PST is the personal storage table, which is a file built by Microsoft to store data from outlook and other services too.  Really quick, this may or may not be an option that you are looking for but, what I would do in my opinion would be to use the PST and export it on a removable USB, since USBs are removeable media.

Given a vector of students, the function FinalAvg is supposed to return the average final exam score across all the students in
alexandr1967 [171]

Answer:

The C++ code is given below with appropriate comments

Explanation:

#define CATCH_CONFIG_MAIN //This tells Catch to provide a main()

#include"catch.hpp" //Header for Catch Framework

double FinalAvg( vector <int> students) // Function to calculate average.

{

double sum =0;

int i;

for( i=0;i<v.size();i++) sum+= v[i];

return v.empty() ? 0.0 : (double(sum)/ v.size());

}

vector<int> func(int argvq[ ]) // This function is made because we can not provide vector in command line argument that's why we used array which is then conerted into vector.

{

vector<int> v;

int j;

int l= sizeof(argvq)/sizeof(argvq[0]);

for(j=0;j<l;j++)

v.push_back(argq[j]);

return v;

}

TEST_CASE(" Final Average marks are computed","[func]") // TEST_ CASE macro to take one or more arguments

{

REQUIRE( func(9,5,-7) == 7); // We write our individual test assertions using the REQUIRE macro.

REQUIRE(func(2,4,6,-2) ==4);

}

Explanation Using different IDE:

#include<bits/stdc++.h>

using namespace std;

double FinalAvg(vector<int> students)

{

double sum=0;

for(int i=0;i<v.size();i++) sum+= v[i];

return v.empty() ? 0.0 : (double(sum)/v.size());

}

int main()

{

vector<int> v;

int i;

while(cin>>i&&i>0) v.push_back(i);

cout<<Final Avg(v);

return 0;

}
