Algorithms are very important in computer Science. The best criteria of algorithm makes sure that computer will perform in the best possible manner of a given do the given task. In cases where efficiency matter a proper algorithm is really important to be used. An algorithm is im-portant in optimizing a computer program according to the available resources. Ultimately when anyone decides to solve a problem through better algorithms then searching for the best combination of program speed and least amount of memory consumption is desired. The way we think about programming has undergone many changes in the years since the first elec-tronic computers required patch cables and switches to convey instructions from human to machine. As is the case with different perspectives of society, changes in computing technolo-gy provide computer scientists with a growing number of tools and platforms on which to practice their craft. Advances such as faster processors, high-speed networks, and large memory capacities have created a spiral of complexity through which computer scientists must navigate. Throughout all of this rapid evolution, a number of basic principles have re-mained constant. The science of computing is concerned with using computers to solve problems
