WebImagine an algorithm that requires a certain but unknown number of iterations to complete. It operates on two inputs, a variable p such that p is a perfect square and a constant k such that k is strictly less than √ p. The size of p decreases by either √ p or (2√ p) - 1 on each iteration until, in the worst case, it reaches k, at which ... WebEngineering Data Structures and Algorithms Hard computation. How hard is it to compute nl-n(n-1)(n-2)... (2)(1)? Do you think there is a polynomial-time algorithm for computing n!? Why or why not? Think about the number of stepa needed to carry out that many multiplications. For example, would you want to find 100! by hand?
