There is an array A[N] of N numbers. You have to compose an array Output[N] such that Output[i] will be equal to multiplication of all the elements of A[N] except A[i]. For example Output[0] will be multiplication of A[1] to A[N-1] and Output[1] will be multiplication of A[0] and from A[2] to A[N-1].
Solve it without division operator and in O(n).
A man has two cubes on his desk. every day he arranges both cubes so that the front faces show the current day of the month. what numbers are on the faces of the cubes to allow this?
Two boys walking in the woods decide to take a shortcut thru a railroad tunel. When they had walked 2/3 of the way, their worst fears were realized. A train was coming in the opposite direction, nearing the tunnel entrance. They boys panicked and each ran for a different end of the tunnel. Both boys ran at the same speed, 10 miles per hour Each boy escaped from the tunnel just at the instant the train would have squashed him. Assuming the train's speed was constant, and both boys were capable of instantaneous reaction and acceleration, how fast was the train going?
Assume your computer is reading characters one by one from a stream (you don't know the length of the stream before ending). Note that you have only one character of storage space (so you cannot save the characters you've read to a something like a strong). When you've finished reading you should return a character out of the stream with equal probability.
Given a set of KEY->VALUE pairs such that each KEY is unique, describe a method of storing these pairs on disk, and a method for accessing the corresponding VALUE given a KEY. Assume that RAM is fixed at 1gb and the set of pairs requires 40gb.
