Answer:
// code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
// variables
int n;
cout<<"Enter a positive number:";
// read number
cin>>n;
// check number is positive or not
while(n<0)
{
// if number is negative
cout<<"Wrong input!!"<<endl;
// ask again to enter again
cout<<"Enter again:";
// read number again
cin>>n;
}
// generate random number between 1 to n
int ran=rand()%n +1;
// print random number
cout<<"Random number between 1 to "<<n<<" is: "<<ran<<endl;
return 0;
}
Explanation:
Read a number from user.Then if input number is negative then ask user to enter a positive number again.After this generate a random number between 1 to n.Print that random number.
Output:
Enter a positive number:-12
Wrong input!!
Enter again:9
Random number between 1 to 9 is: 2
Answer:
Explanation:
The following code is written in Java. Both functions traverse the linkedlist, until it reaches the desired index and either returns that value or deletes it. If no value is found the function terminates.
public int GetNth(int index)
{
Node current = head;
int count = 0;
while (current != null)
{
if (count == index)
return current.data;
count++;
current = current.next;
}
assert (false);
return 0;
}
public int removeNth(int index)
{
Node current = head;
int count = 0;
while (current != null)
{
if (count == index)
return current.remove;
count++;
current = current.next;
}
assert (false);
return 0;
}
