Minimum Subarray
Given an array of integers, find the subarray with smallest sum.
Return the sum of the subarray.
For [1, -1, -2, 1], return -3
The subarray should contain at least one integer.
////If sum is greater than 0, it is not useful for the rest of numbers, so , get rid of it , set it as 0
////keep summing up the next one , if it is less than 0, keep it, keep summing next number.
public class Solution { /** * @param nums: a list of integers * @return: A integer indicate the sum of minimum subarray */ public int minSubArray(ArrayList<Integer> nums) { // write your code int sum=nums.get(0); int minSum=nums.get(0); for(int i=1;i<nums.size();i++) { if(sum>0) sum=0; sum=sum+nums.get(i); minSum=Math.min(minSum,sum); } return minSum; } }
