## 思路 $O(N)$ $O(1)$
跟[0767. Reorganize String](https://hackmd.io/Cs2YBT2RQHOFLNcLLFBPOQ), [1054. Distant Barcodes](https://hackmd.io/5RbR4Q9pRBKgIMKYQjgxQg)差不多
都是先找到最大的，如果最大的比total的一半大，说明有一部分排不进去，先排最大的，然后再把其他的塞进去
## Code

class Solution {
    public long numberOfWeeks(int[] milestones) {
        long ans = 0;
        int max = 0;
        for(int milestone:milestones){
            ans += (long)milestone;
            max = Math.max(max, milestone);
        }
        if(max > (ans+1)/2) return ans-(2*max-ans-1);
        else return ans;
    }
}
