find_all elements in an array that match a condition? I've an array of hash entries, and want to filter based on a paramater passed into the function. If there are three values in the hash, A, B, and C, I want to do something similar to: find all where A......

The 2D Point data type can consist of: data values: (0,0),(1,0),(3.7,−8.5)··· operations: get distance between 2 points, move point, add points together, ... Data Structures: Familiar examples Example (Data Structure: Array) ...
A linked cursor implementation within an array for the binary search treedata type (ADT) is used ASA case study. The proofs of correctness for the ADT operations are given in a careful, but informal style consistent with the level of formality common in discrete mathematics and calculus courses...

To implement disjoint set ADT, an array is enough also. ADT set is an auxiliary data structure used to solve many algorithmic problems based on graphs.Disjoint Sets ADTThe basic operations on a disjoint set are the below ones:MAKESET(X): create a new set with element X UNION(X, Y): ...
