Creating robust software requires the use of efficient algorithms, but programmers seldom think about them until a problem occurs. This updated edition of *Algorithms in a Nutshell* describes a large number of existing algorithms for solving a variety of problems, and helps you select and implement the right algorithm for your needs—with just enough math to let you understand and analyze algorithm performance.

With its focus on application, rather than theory, this book provides efficient code solutions in several programming languages that you can easily adapt to a specific project. Each major algorithm is presented in the style of a design pattern that includes information to help you understand why and when the algorithm is appropriate.

With this book, you will:

- Solve a particular coding problem or improve on the performance of an existing solution
- Quickly locate algorithms that relate to the problems you want to solve, and determine why a particular algorithm is the right one to use
- Get algorithmic solutions in C, C++, Java, and Ruby with implementation tips
- Learn the expected performance of an algorithm, and the conditions it needs to perform at its best
- Discover the impact that similar design decisions have on different algorithms
- Learn advanced data structures to improve the efficiency of algorithms

then crash, often with disastrous consequences. One might write a program to monitor memory allocations and deallocations and report on a program's memory profile in order to detect the presence of memory leaks. Such a memory profiler can be written quite simply by writing new malloc() and free() functions that record the appropriate information before allocating and freeing memory. We want to record every memory allocation and when that memory is freed, we must remove it from the set of active

of 1≤j≤m partners, tj∈T; and a set of 1≤k≤p acceptable pairs, pk∈P, that associate an element si∈S with a partner tj∈T. The sets S and T are disjoint, which gives this problem its name. Output A set of pairs (si,tj) selected from the original set of acceptable pairs, P. These pairs represent a maximum number of pairs allowed by the matching. The algorithm guarantees that no greater number of pairs is possible to be matched (although there may be other arrangements that lead to the same number
