Slate (writing) expensive. Slate (writing) A slate is a thin piece of hard flat material, such as the rock also called slate, that is used as a medium for writing. The rock is “a metamorphic rock created by the recrystallization of the minerals in shale from clay to parallel-aligned, flat, flake-like minerals such as mica”. The writing slate consisted of a piece of slate, typically either 4x6 inches or 7x10 inches, encased in a wooden frame. A precise date range for writing slates of this type has not been established. Usually, a piece of cloth or slate sponge was used to clean
Stooge sort Stooge sort Stooge sort is a recursive sorting algorithm. It is notable for its exceptional bad time complexity of . The running time of the algorithm is thus slower compared to reasonable sorting algorithms, and is slower than Bubble sort, a canonical example of a fairly inefficient sort. It is however more efficient than Slowsort. The name comes from The Three Stooges. The algorithm is defined as follows: It is important to get the integer sort size used in the recursive calls by rounding the 2/3 "upwards", e.g. rounding 2/3 of 5 should give 4 rather than 3, as otherwise
