Answer and Explanation:
To calculate Big O, go through each line of code and determine O(!), O(n) and return your calculation.
For example,
In O (5 +6n), where 6 5 represent five instances of O(1), and 6 represent the 6 O(n).
We compute the time complexity of the algorithm. We get the result, just an estimation. In given algorithms, run time in milliseconds has been provided, such as in T (1) algorithm process in 512 milliseconds and T(2) algorithms process 8129 milliseconds. But big O notation not measured in milliseconds. Information given is not enough to calculate the big O notation.
Answer:
6048 hours is required to guarantee access to the database
Explanation:
If a password contains 8 distinct digits, then there are P(10,8) permutations possible
P(10,8)=10! / (10-8)! = 10!/2! = 1814400
Since it takes 12 seconds to try one combination,
1814400×12 = 21772800 seconds is required to guarantee access to the database. This is
