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; } }
