Write a recursive function that calculates if two binary trees are similar?
ahrayia [7]

Answer:

bool identicaltrees(Node* root1,Node* root2)//function of type boolean true if idenctical false if not.

{

   if(root1==NULL&&root2==NULL)//both trees are null means identical.

   return true;

   if(roo1 && root2)

   {

       if(root1->data==root2->data)//condition for recursive call..

       {

           return (identicaltrees(root1->left,root2->right)&&identicaltrees(root1->right&&root2->right);

       }

   }

   else

   return false;

}

Explanation:

In this function it of type boolean returns true if both the trees are identical return false if not.First we are checking root node of both the trees if both are null then they are identical returning true.

If both root nodes are not null then checking their data.If data is same then recursively traversing on both trees and checking both trees.

else returning false.

Suppose that a 64MB system memory is built from 64 1MB RAM chips. How many address lines are needed to select one of the memory
alexdok [17]

Answer:

6 address lines

Explanation:

The computation of the number of address lines needed is shown below:

Given that

Total memory = 64MB

= 2^6MB

=2^{26} bytes

Also we know that in 1MB RAM the number of chips is 6

So, the number of address lines is 2^{26} address i..e 26 address lines

And, the size of one chip is equivalent to 1 MB i.e. 2^{20} bytes

For a single 1MB chips of RAM, the number of address lines is

\frac{2^{26}}{2^{20}} \\\\= 2^6 address

Therefore 6 address lines needed
