Leftist heaps

Leftist heaps. Background. A binary min-heap allows the operations of push and pop to occur in an average case of Q (1) and Q ( ln ( n )) time, respectively Merging two binary min-heaps, however, is an Q ( n ) operation

Recursion

Recursion. Definitions I. A recursive definition is a definition in which the thing being defined occurs as part of its own definition Example: A list consists of: An open parenthesis, "(" Zero or more atoms or lists, and A close parenthesis, ")". Definitions II.

Conditional & Joint Probability

Conditional & Joint Probability. A brief digression back to joint probability: i.e. both events O and H occur. Again, we can express joint probability in terms of their separate conditional and unconditional probabilities. This key result turns out to be exceedingly useful!.
