    I have the same problem of this testing case

    S

    I have figured it out. I misunderstood the requirement. It is the subarray not the number of the elements.


  • 0
    N

    public class Solution {
    public int minSubArrayLen(int s, int[] nums)
    {
    int n = nums.length;
    if(n == 0)
    return 0;
    int len = n + 1;
    int start = 0;
    int sum = 0;
    for(int i = 0;i <= n - 1;i++)
    {
    sum += nums[i];
    while(sum >= s)
    {
    len = (len < i - start + 1) ? len:i - start + 1;
    sum -= nums[start];
    start++;
    }
    }
    return (len == n + 1) ? 0:len;
    }
    }

    I have the same error as yours. I don't understand. What is the reason?
