Introduction Fisher’s exact test is a statistical significance test used to determine if there are nonrandom associations between two categorical variables. Unlike the chi-square test of independence, which may not perform well with small samples or low expected...

Introduction Interpolation Search is an efficient search algorithm for uniformly distributed, sorted datasets. While binary search divides the search range in half each time, interpolation search goes a step further by estimating the position of the target value based...

Sorting algorithms are essential in computer science for organizing data efficiently. Selection Sort is a simple, comparison-based sorting algorithm that repeatedly selects the smallest (or largest) element from the unsorted portion of the list and moves it to the...

Introduction Merge Sort is a classic and highly efficient sorting algorithm based on the divide and conquer paradigm. It splits an array into smaller subarrays, recursively sorts those subarrays, and then merges them back together in a sorted manner. Merge Sort...
