Answer:
Starting from root, recursively traverse the min-heap. Once we find a key with value less than our X, we know that every key in subtree of that key will be also smaller than our X. Otherwise, we should keep traversing.
Explanation:
The complexity of this algorithm will be O(N) where N is the number of keys in our min-heap.
Answer:
The correct answer for the following question will be Digital certificate.
Explanation:
An electronic "password" that allows an organization or person to exchange information (data) with security using the public key infrastructure (PKI) over the internet called as Digital certificate. And is also known as Public key certificate and identity certificate.
Digital certificate contains the following things :
- Copy of certificate holder public key.
- Name of certificate holder.
- Serial number which is used to uniquely identify a certificate.
- Expiration dates.
- Digital signature of certificates.
What security provided :
- Identification/Authentication.
- Access Control.
- Non-Repudiation.
- Integrity.
Answer:
128 bits
Explanation:
The MD5, which is the acronym for Message-Digest algorithm 5, invented by a professor of MIT, Ronald Rivest, is a cryptographic hash algorithm that creates a 128 bit hash value and is typically represented as a 32 character hex number. MD5 is the improved version of MD4 which was also created by the same professor.
Following is an example format of an MD5 hash;

MD5 has been proven to have security issues. One of these issues is called collision attack - a situation where the same hash is produced for different input data.
