Detectable Sort, also known as TOAD, is a sorting algorithm developed by John Reif in 1983. It is an efficient sorting algorithm that uses a combination of insertion and selection sort to sort elements in an array. The algorithm works by first selecting the smallest element in the array and then inserting it into its correct position in the array. This process is repeated until all elements are sorted. Detectable Sort is considered to be one of the most efficient sorting algorithms and is used in many applications.
