Find the contiguous subarray within an array (containing at least one number) which has the largest product.
For example, given the array [2,3,-2,4]
,
the contiguous subarray [2,3]
has the largest product = 6
.
C++实现代码:
#include<iostream> using namespace std; class Solution { public: int maxProduct(int A[], int n) { if(n==0) return 0; int maxPro[n]; int minPro[n]; minPro[0]=maxPro[0]=A[0]; int i; for(i=1;i<n;i++) { maxPro[i]=max(A[i],max(maxPro[i-1]*A[i],minPro[i-1]*A[i])); minPro[i]=min(A[i],min(maxPro[i-1]*A[i],minPro[i-1]*A[i])); } int max=maxPro[0]; for(i=0;i<n;i++) { if(max<maxPro[i]) max=maxPro[i]; } return max; } }; int main() { Solution s; int arr[10]={2,3,-2,4}; cout<<s.maxProduct(arr,4)<<endl; }
