What is penetration testing? Penetration testing (or pen testing) is a security exercise where a cyber-security expert attempts to find and exploit vulnerabilities in a computer system. The purpose of…
Introduction Reversing a string is a common task in programming that involves rearranging the characters of the string so that they appear in the opposite order. This operation can be…
Introduction In a square matrix, the diagonal elements are those that extend from the top left corner to the bottom right corner. For example, in a n×nn \times nn×n matrix,…
Introduction In linear algebra, triangular matrices are special types of square matrices. An upper triangular matrix is a matrix in which all the entries below the main diagonal are zero.…
Introduction A symmetric matrix is a square matrix that is equal to its transpose. In other words, for a matrix AAA to be symmetric, it must satisfy the condition A=AA…
Introduction Matrix multiplication is a fundamental operation in linear algebra where two matrices are multiplied to produce a third matrix. This operation is crucial in various applications, including computer graphics,…
Introduction Linear search is a straightforward algorithm for finding a specific value within an array. It sequentially checks each element until the desired value is found or the end of…
Introduction Binary search is an efficient algorithm for finding a specific value in a sorted array. It works by repeatedly dividing the search interval in half. If the value of…
Introduction Matrix addition is a fundamental operation in linear algebra where two matrices of the same dimensions are added together by adding their corresponding elements. This operation is commonly used…
Introduction Matrix subtraction is an operation that involves subtracting the corresponding elements of two matrices of the same dimensions. This operation is widely used in fields such as computer graphics,…
