最大连续子数组的和（记录子数组范围）

public class Main {public static void main(String[] args){Main m=new Main();int[] arr={1,-2,3,10,-4,-3,2,-5};maxSeq(arr);}public static int maxSeq(int[] arr){int n=arr.length;int sum=0;int max=Integer.MIN_VALUE;int start=0,end=0;for(int i=0;i<n;i++){if(sum>=0){//end++;sum=sum+arr[i];}else{start=i;end=i+1;sum=arr[i];}if(max<sum){end=i+1;max=sum;}}System.out.println(max);System.out.println("下标从"+start+"到"+(end-1));return max;}}
