C's qsort command can be used for array sorting. Optimal sorting algorithms run in O(n log(n)) comparisons. Radix Sort can sometimes perform better than O(n log(n))

Membership operators check if a value is present in a collection. Operators use binary syntax with target value and collection. Expressions always evaluate to True or False
Array is a collection of elements of same memory size identified by indices. Elements are stored using mathematical formulas to compute their positions. Arrays are among oldest and most important data structures. Modern computers use one-dimensional array of words as memory
Concision eliminates redundancy by using fewest words while preserving meaning. Principle achieved through omission of obvious or irrelevant information. Example: "Most arguments must demonstrate their truth to readers"
