C Programming: Find First Unique Character in a String
Introduction Finding the first non-repeated (unique) character in a string is a simple yet important problem in programming. In this task, you need to find the first character in a…
C is widely used in developing operating systems (like UNIX), embedded systems, and high-performance applications. Its influence can also be seen in many modern programming languages, including C++, C#, and Java.
Introduction Finding the first non-repeated (unique) character in a string is a simple yet important problem in programming. In this task, you need to find the first character in a…
Introduction A spiral matrix is two-dimensional. To create it, you fill the array with numbers in a spiral pattern. Starting at the top-left corner, the numbers move right, followed by…
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…
