Baptism of the soul, practice python (6)-live code + list, python live Active usage: Use input built-in functions Note: In python2 and python3, the input function is not the same. In python2, the input type is the same as the input type, and in python3, the input type is the string, this is the same as the raw_input function in python2, and there is no raw_input

Python code example for implementing heap and index heap and python index heap A heap is a Complete Binary Tree. A heap is divided into a large root heap and a small root heap. A large root Heap has a parent node greater than the left and right subnodes, and the left and right Subtrees also meet the full Binary Tree of this type. Opposite to the small root heap.
