COMPUTER SCIENCE Which expression is true approximately 66% of the time? a) random() >= 66 b) random() < 0.66 c) random() < 66 d) random() >= 0.66 Verified answer COMPUTER SCIENCE Use the following ideas to develop a nonrecursive, linear-time algorithm for the maximum-subarray problem. Start at the left end of the array, and progress toward the right, keeping track of the maximum subarray seen so far. Knowing a maximum subarray of A[1..j], extend the answer to find a maximum subarray ending at index j + 1 by using the following observation: a maximum subarray of A[1..j + 1] is either a maximum subarray of A[1..j] or a subarray A[i..j + 1], for some 1 ≤ i ≤ j + 1. Determine a maximum subarray of the form A[i..j + 1] in constant time based on knowing a maximum subarray ending at index j.
