Looking through the options, we can conclude that:
d. double temp;
..... is not a part of the method
Answer:
Honeytoken
Explanation:
Honeytokens (aka honey traps or honeypots) may be described as bogus or dummy IT resources which are created or placed in a system or network for the sole purpose of attracting the attention of cyber-criminals and being attacked. These might be servers, applications, complete systems or datasets which are placed online (via the public internet, or a public-facing gateway to a private network), in order to attract cyber-attackers.
Honeytokens may be specifically defined as pieces of data which on the surface look attractive to potential attackers, but actually have no real value – at least, not to the attacker. For the owners of the tokens (i.e. the people who set the trap), they can be of great value, as they contain digital information which is monitored as an indicator of tampering or digital theft.
Answer:
The power function can be written as a recursive function (using Java) as follows:
- static int power(int x, int n)
- {
- if(n == 0){
- return 1;
- }
- else {
- return power(x, n-1 ) * x;
- }
- }
Explanation:
A recursive function is a function that call itself during run time.
Based on the question, we know x to the 0th power is 1. Hence, we can just create a condition if n = 0, return 1 (Line 3 - 5).
Next, we implement the logic "x to the nth power can be obtained by multiplying x to the n-1'th power with x " from the question with the code: return power(x, n-1 ) * x in the else block. (Line 6 -8)
In Line 7, power() function will call itself recursively by passing x and n-1 as arguments. Please note the value of n will be reduced by one for every round of recursive call. This recursive call will stop when n = 0.
Just imagine if we call the function as follows:
int result = power(2, 3);
What happen will be as follows:
- run Line 7 -> return power(2, 2) * 2
- run Line 7 -> return power(2, 1) * 2
- run Line 7 -> return power(1, 0) * 2
- run Line 4 -> return 1 (Recursive call stop here)
Next, the return value from the inner most recursive call will be return to the previous call stack:
- power(1, 0) * 2 -> 1 * 2
- power(2, 1) * 2 -> 1 * 2 * 2
- power(2, 2) * 2 -> 1 * 2 * 2 * 2 - > 8 (final output)
