We usually say "sort", refers to the internal sort, that is, using memory resources to sort. In addition to the internal ordering, there is an external sort. This article mainly describes the internal sorting.Internal sorting is divided into insert

1. Brief Introduction Assume that the array to be sorted is int array [] and the array length is n.It mainly utilizes the nature of the heap. Use the largest heap for ascending sorting.First, build a heap and use the recursive root order traversal

The Maximum SubarrayFind the contiguous subarray within an array (containing at least one number) which have the largest sum.e.g. [−2,1,−3,4,−1,2,1,−5,4] -> [4,−1,2,1] = 6 .1 Public voidMaxsubsimple (int[] Array) {2 if(Array = =NULL||
