Answer:

For any loop, we find out the runtime of the block inside them and multiply it by the number of times the program will repeat the loop. All loops that grow proportionally to the input size have a linear time complexity O(n) . If you loop through only half of the array, that's still O(n) .

What are the advantages and disadvantages of using steganography versus symmetric or asymmetric encryption

ankoles [38]

Explanation:

Steganography is a technique used in securing or hiding sensitive information by encrypting the information in a non-hidden file like a JPEG format. A major advantage of this method is that it reduces the risk of attack or break-in since the data is enclosed in a non-secure file; thereby reducing threats of any hack. One main disadvantage of this method is that the hidden message may become difficult to recover if the source file (non-secure file) used, is edited or deleted.

In symmetric or asymmetric encryption they both employ cryptographic encryption method. While symmetric encryption uses one key to encrypt and decrypt data, asymmetric encryption uses two keys (one for encryption, the other for decryption) of the data. A major advantage of using these methods is that they provide more security. Although while symmetric encryption is faster, asymmetric encryption is slower (eg using separate keys to gain access), a disadvantage.

Which three steps might be included in an algorithm for a digital thermostat?

chubhunter [2.5K]

Answer:

Explanation:

It certainly isn't D. It would cost a fortune to make that happen. It's not impossibe. Just impractical.

It's not A. Resistance is a floating physical thing present in the air.

B could be correct, but there is a better answer.

The answer is C. A thermistor is a resistance that is temperature sensitive.
