Its use of the message digest 5 (MD5) hash algorithm for security.
CHAP uses a combination of MD5 hashing and a challenge-response mechanism, and authenticates without sending passwords as plaintext over the network. The security of the MD5 hash function is severely compromised.
The recursive function would work like this: the n-th odd number is 2n-1. With each iteration, we return the sum of 2n-1 and the sum of the first n-1 odd numbers. The break case is when we have the sum of the first odd number, which is 1, and we return 1.
int recursiveOddSum(int n) {
if(2n-1==1) return 1;
return (2n-1) + recursiveOddSum(n-1);
}
To prove the correctness of this algorithm by induction, we start from the base case as usual:
by definition of the break case, and 1 is indeed the sum of the first odd number (it is a degenerate sum of only one term).
Now we can assume that 
returns indeed the sum of the first n-1 odd numbers, and we have to proof that 
returns the sum of the first n odd numbers. By the recursive logic, we have
and by induction, is the sum of the first n-1 odd numbers, and 2n-1 is the n-th odd number. So, is the sum of the first n odd numbers, as required:
<u>Virus outbreaks in an organization:</u>
In an organization end user who uses the computer or laptop or workstation is not aware of virus outbreaks. So As IT administrator of an organization she/he has aware of latest virus attack and rectification solution before outbreaks.
Common causes for this virus outbreaks problem is update virus definition or database. Update operating system patches on regular basis.
Installation appropriate anti-virus in each workstation or desktop or laptop and scheduling virus scanning and take necessary steps.
To address and troubleshoot disconnect workstation and desktop or laptop from LAN. Uninstalled unnecessary software, delete temp folder contents.
