What does the following C expression do? x = (x << 1) + x + (x >> 1);

Consider the matrices A, B, C, and D, which are 20 x 15, 15 x 30, 30 x 5, and 5 x 40 matrices, respectively. What is the minimum number of multiplications required to multiply these four matrices?

Consider two decision problems Q1, Q2 such that Q1 reduces in polynomial time to 3-SAT and 3-SAT reduces in polynomial time to Q2. Then which one of the following is consistent with the above statement?

What is the recurrence relation for the worst-case time complexity of QuickSort, and what is the time complexity in the worst case?

In an adjacency list representation of an undirected simple graph G = (V, E), each edge (u, v) has two adjacency list entries: [v] in the adjacency list of u, and [u] in the adjacency list of v. These are called twins of each other. A twin pointer is a pointer from an adjacency list entry to its twin. If |E| = m and |V | = n, and the memory size is not a constraint, what is the time complexity of the most efficient algorithm to set the twin pointer in each entry in each adjacency list?
