Inspired by Python's heapq module, Heapify is a Ruby library that provides methods to transform an array into a min heap. A min heap is a binary tree where the parent node is less than or equal to its children. The API below differs from textbook heap algorithms in two aspects: (a) ...
I am sorry, but in the Python 2.4 description of "heapify", I find the description of "Transform list x into a heap, in-place, in linear time," unbelievable. I understand the hand-wave that makes dictionary building linear (though I have a hard time with even that). Could somebody te...
