算法99---丰收（网易笔试）--二分查找

思路：

加和+二分查找

 

 代码：

n = int(input())
ns = list(map(int, input().split()))
m = int(input())
q = list(map(int, input().split()))
 
for i in range(1, n):
    ns[i] += ns[i-1]
for i in q:
    l, r =0, n-1
    while l < r:
        mid = (l +r) >> 1
        if ns[mid] < i:
            l = mid + 1
        else:
            r = mid
    print(r + 1)
