What algorithms should a first year computer science student know?

FIFO : first in first out 

LIFO: last in first out 

Simple start-up algorithms like searching, sorting, hashing are much essential to first year students.  

Linked List, Stack, Queue, Binary Search tree

I fully agree with the answers been added by EXPERTS....................Thanks.

The most common algorithm is called a recipe procedure, which is performed in an automatic way to solve a particular task. This recipe proceedings should be sufficiently precise to use it consisted only of automatically executing instructions provision. This assumes that some of the original instructions for this provision is feasible, it means that they are defined and the algorithm does not have to define them, but you can use them.Algorithmics is more than the IT department. It lies at the heart of all the departments of computer science and in all honesty can say about it that is important for the majority of mathematics and natural sciences, economics and technology. The very nature of algorithms makes it particularly suitable for use in these disciplines that benefit from the use of computers; such disciplines overwhelming majority.A word about the programming language C ++. The author of C ++ programming language is Bjarne Stroustrup. C ++ is in widespread use since the early eighties. C ++ is a significant extension of the C language, but retained the C language as a subset of C ++ with an accuracy of nearly one hundred percent.
