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.
Suppose that objects A, B, and C are instances of class MyClass (MyClass A, B, C;). How should you design an assignment operator so that the "A=B=C;" statement would be allowed by a compiler but "(A=B)=C;" would not be allowed by a compiler?
Given a dictionary of millions of words, write a program to find the largest possible rectangle of letters such that every row forms a word (reading left to right) and every column forms a word (reading top to bottom).
Print all combinations of M members of a set of N elements in a sequence such that each set can be obtained from the previous set by deleting one member and adding one member.
Design and describe a system/application that will most efficiently produce a report of the top 1 million search requests. You are given:
1. You are given 12 servers to work with. They are all dual-processor machines with 4Gb of RAM, 4x400GB hard drives and networked together.(Basically, nothing more than high-end PC's) 2. The log data has already been cleaned for you. It consists of 100 Billion log lines, broken down into 12 320 GB files of 40-byte search terms per line. 3. You can use only custom written applications or available free open-source software.
