When it comes to analysing the complexity of any algorithm in terms of time and space, we can never provide an exact number to define the time required and the space required by the algorithm, instead we express it using some standard notations, also known as Asymptotic Notations. When we analyse any algorithm, we generally get a formula to represent the amount of time required for execution or the time required by the computer to run the lines of code of the algorithm, number of memory accesses, number of comparisons, temporary variables occupying memory space etc. This formula often contains unimportant details that don't really tell us anything about the running time. Also, When we compare the execution times of two algorithms the constant coefficients of higher order terms are also neglected.

Floor and Ceiling Functions: If x is a real number, then it means that x lies between two integers which are called the floor and ceiling of x. If x is a real number, then integer function INT x will convert x into integer and the fractional part is removed.

The absolute function ABS x or x gives the absolute value of x i. The symbol which is used to denote summation is a Greek letter Sigma?. Let a1, a2, a3, ….. Let we have a set of n elements. A permutation of this set means the arrangement of the elements of the set in some order. Suppose the set contains a, b and c. The various permutations of these elements can be: abc, acb, bac, bca, cab, cba. If there are n elements in the set then there will be n!

It means if the set has 3 elements then there will be 3! Exponent means how many times a number is multiplied by itself. If m is a positive integer, then:. The concept of logarithms is related to exponents. If b is a positive number, then the logarithm of any positive number x to the base b is written as logbx.

It represents the exponent to which b should be raised to get x i. Mathematical notations and functions 1. It is the greatest integer that is not greater than x. It is the smallest integer that is not less than x. Remainder Function Modular Arithmetic : If k is any integer and M is a positive integer, then: k mod M gives the integer remainder when k is divided by M.

Integer and Absolute Value Functions: If x is a real number, then integer function INT x will convert x into integer and the fractional part is removed.

Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity. Big O is a member of a family of notations invented by Paul Bachmann , [1] Edmund Landau , [2] and others, collectively called Bachmann—Landau notation or asymptotic notation. In computer science , big O notation is used to classify algorithms according to how their run time or space requirements grow as the input size grows. Big O notation is also used in many other fields to provide similar estimates. Big O notation characterizes functions according to their growth rates: different functions with the same growth rate may be represented using the same O notation.


usually implemented with dynamic data structures, such as linked lists. Java provides the standard mathematical functions as static methods in class. Math, as listed in Table B //rachaeldohertyfoundation.org [16] A. S. Glassner.

Data Structure is a systematic way to organize data in order to use it efficiently. Following terms are the foundation terms of a data structure. Interface represents the set of operations that a data structure supports. An interface only provides the list of supported operations, type of parameters they can accept and return type of these operations. Implementation also provides the definition of the algorithms used in the operations of the data structure.

Big O notation

Mathematical notation is a system of symbolic representations of mathematical objects and ideas. Mathematical notations are used in mathematics , the physical sciences , engineering , and economics. A mathematical notation is a writing system used for recording concepts in mathematics. The media used for writing are recounted below, but common materials currently include paper and pencil, board and chalk or dry-erase marker , and electronic media.

In computer science , an abstract data type ADT is a mathematical model for data types. An abstract data type is defined by its behavior semantics from the point of view of a user , of the data, specifically in terms of possible values, possible operations on data of this type, and the behavior of these operations. This mathematical model contrasts with data structures , which are concrete representations of data, and are the point of view of an implementer, not a user. Formally, an ADT may be defined as a "class of objects whose logical behavior is defined by a set of values and a set of operations"; [1] this is analogous to an algebraic structure in mathematics. What is meant by "behavior" varies by author, with the two main types of formal specifications for behavior being axiomatic algebraic specification and an abstract model; [2] these correspond to axiomatic semantics and operational semantics of an abstract machine , respectively. Some authors also include the computational complexity "cost" , both in terms of time for computing operations and space for representing values.
