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.
Answer:
negatives = []
zeros = []
positives = []
while True:
number = input("Enter a number: ")
if number == "":
break
else:
number = int(number)
if number < 0:
negatives.append(number)
elif number == 0:
zeros.append(number)
else:
positives.append(number)
for n in negatives:
print(n)
for z in zeros:
print(z)
for p in positives:
print(p)
Explanation:
Initialize three lists to hold the numbers
Create a while loop that iterates until the user enters a blank line
Inside the loop:
If the number is smaller than 0, put it in the negatives list
If the number is 0, put it in the zeros list
Otherwise, put the number in the negatives list
When the while loop is done, create three for loops to print the numbers inside the lists
Answer:
Achieved Instruction per cycle rate is 
Solution:
As per the question:
Execution time, t = 1.4 s
No. of instructions being executed, n = 1.8 billion =
Clock speed of CPU, f = 3.2 GHz = 
Now, to calculate the actual issue rate achieved:
CPI (Cycle per Instruction) = 
CPI = 
Instruction per cycle is given as the reciprocal of CPI:
Instruction per cycle = 
In C++, 'Try block' comprises of a group of statements in which there is a probability of an exception to take place.
C). The statements that would be left in the try block in case a particular statement leads to an exception 'can't be executed.'
- In case an exception takes place, the left statements in the try block fail to function.
- This is the primary reason for which a catch block immediately succeeds a try block in order to deal with the exception and help close that code to allow the statements to work.
- Thus, <u>option C</u> is the correct answer.
