Basic idea:The bubble sort is implemented by exchanging two elements, the idea being:The first trip will be sorted sequence (a[0]~a[n-1]) from the go, 22 adjacent elements to compare, if the latter small, then exchange, compare n-1 times;At the end

Basic idea:The basic idea is basically two points: build the initialization heap and sort.To build the largest heap as an example, there are several steps that can be divided into the following:1, the initial sequence to be sorted (a0,a1,a2 .... An-1
