Expert Solution
Step 1 ::
- We have to code for the number 2 problem for logarithmic problem using python.
- For this problem we will use the Shanks' baby-step giant-step algorithm.
The algorithm starts by computing two lists of values: the baby steps and the giant steps. The baby steps are the values of a^i for i from 0 to m-1, where m is typically the square root of p. The giant steps are the values of b * a^(-im) for i from 0 to m-1.
The algorithm then sorts the baby steps list and searches for each giant step value in the baby steps list using binary search. If a match is found, the algorithm computes the value of x as i * m + j, where j is the index of the matching baby step.
