So we can start b-search on string length of s1, for s2, since current substr len is fixed, we use rolling-hash to check match. Also, another interesting point to handle collision in a typical BK algorithm: we use double hashing to avoid collision, instead of a O(n) brutal-force str...

The jj-th of them should be equal to the minimum number of pipes to turn on so that after tjtj seconds all of the locks are filled. If it is impossible to fill all of the locks in given time, print −1−1. Examples Input 5 4 1 5 4 1 6 1 6 2 3 4 5 Output -1 3...
The main tabu search procedure seeks to improve the selection of clusters. If this fails, a MILP is applied to solve a simplified model in which clusters are partially fixed to take larger steps in the search space. Pěnička, Faigl, & Saska (2019) propose a VNS that operates on the...
Five rather different multistart tabu search strategies for the unconstrained binary quadratic optimization problem are described in [21]. For the NP-hard min-bisection problem, a deterministic annealing algorithm based on a logarithmic-cosine barrier function is developed in [22]. In [23] a set ...
Give recurrences for the worst-case running times of binary search when arrays are passed using each of the three methods above, and give good upper bounds on the solutions of the recurrences. Let N be the size of the original problem and n be the size of a subproblem. b. Redo part (...
Given the root to a binary search tree, find the second largest node in the tree. Solution Problem 37 This problem was asked by Google. The power set of a set is the set of all its subsets. Write a function that, given a set, generates its power set. ...
