Answer:
The answer is: c. Adding external CSS is a good practice for various reasons, including code organization.
Explanation:
External CSS improves maintainability in code.
Internal CSS has precedence over external CSS, it means that internal will overwrite external CSS, but abuse of internal CSS often makes hard to maintain HTML code on a large website.
Furthermore, it is much easier to modify one CSS(external) file that can impact multiple web pages than go into every HTML page and modify your styles per page. Many sites have hundred or more pages, go through each one wouldn't be productive.
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: rootkit
Explanation:
Hi, A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or an area of its software that is not otherwise allowed (for example, to an unauthorized user) and often masks its existence or the existence of other software.
A rootkit provides continued privileged access to a computer while hiding its presence. Because of this hiding characteristic it is very difficult to detect.
Once a rootkit has been installed, it allows someone to have total remote control of a computer and do things such as files executions and system changes.
