In this example, we will consider a dictionary consisting of the following words: {a, ab, bab, bc, bca, c, caa}. The graph below is the Aho–Corasick data structure constructed from the specified dictionary, with each row in the table representing a node in the trie, with the column path indicating the (unique) sequence of characters from the root to the node.

The procedure begins by examining the key; null denotes the arrival of a terminal node or end of a string key. If the node is terminal it has no children, it is removed from the trie (line 14). However, an end of string key without the node being terminal indicates that the key does not exist, thus the procedure does not modify the trie.
dkLen is the desired bit-length of the derived key; DK is the generated derived key; Each hLen-bit block T i of derived key DK, is computed as follows (with + marking string concatenation): DK = T 1 + T 2 + ⋯ + T dklen/hlen T i = F(Password, Salt, c, i) The function F is the xor (^) of c iterations of chained PRFs.
Here, the list [0..] represents , x^2>3 represents the predicate, and 2*x represents the output expression.. List comprehensions give results in a defined order (unlike the members of sets); and list comprehensions may generate the members of a list in order, rather than produce the entirety of the list thus allowing, for example, the previous Haskell definition of the members of an infinite list.
Multi-key quicksort, also known as three-way radix quicksort, is an algorithm for sorting strings. This hybrid of quicksort and radix sort was originally suggested by P. Shackleton, as reported in one of C.A.R. Hoare 's seminal papers on quicksort ; [2] : 14 its modern incarnation was developed by Jon Bentley and Robert Sedgewick in the mid ...

The compiler uses argument-dependent lookup to resolve the begin and end functions. The C++ Standard Library also supports for_each, that applies each element to a function, which can be any predefined function or a lambda expression. While range-based for is only from the start to the end, the range or direction can be changed by altering the ...
