  • Notes om Hash Table

    A hash function is any function that maps a data set of an arbitrary size to a data set of a fixed size that falls into the hash table. the values returned by a hash function are called hash values, hash codes, hash sums, or simply hashes. with a c++ program to demonstrate.

  • Notes on Infix To Postfix Conversion

    We, humans, know how to interpret the infix notation, as that's what we are taught in schools. but this form is not very suitable for the computer to read and evaluate the expressions, because each operator has a precedence, which shows the order in which the expression needs to be evaluated.

  • Algorithms and Time Complexity

    In computer science, the time complexity is the computational complexity that measures or estimates the time taken for running an algorithm. time complexity is commonly estimated by counting the number of elementary operations performed by the algorithm, supposing that an elementary operation takes a fixed amount of time to perform.

  • Notes on Python Data Types

    Type represents the kind of value and determines how the value can be used. all data values in python are encapsulated in relevant object classes. everything in python is an object and every object has an identity, a type, and a value. like another object-oriented language such as java or c++, there are several data types which are built into python. extension modules which are written in c, java, or other languages can define additional types.

  • Notes on RSA Cryptosystem

    Rsa is one of the first public-key (asymmetric) cryptosystems and is widely used for secure data transmission. rsa stands for rivest-shamir-adleman, initial letters of the surnames of its creators. this asymmetry is based on the practical difficulty of the factorization of the product of two large prime numbers, the "factoring problem".
