题目描述
Bizon the Champion is called the Champion for a reason.
Bizon the Champion has recently got a present — a new glass cupboard with n shelves and he decided to put all his presents there. All the presents can be divided into two types: medals and cups. Bizon the Champion has _a_1 first prize cups, _a_2 second prize cups and _a_3 third prize cups. Besides, he has _b_1 first prize medals, _b_2 second prize medals and _b_3 third prize medals.
Naturally, the rewards in the cupboard must look good, that's why Bizon the Champion decided to follow the rules:
- any shelf cannot contain both cups and medals at the same time;
- no shelf can contain more than five cups;
- no shelf can have more than ten medals.
Help Bizon the Champion find out if we can put all the rewards so that all the conditions are fulfilled.
冠军比松之所以被称为冠军,是有原因的。
最近,冠军比松收到了一份礼物——一个有 n 层架子的新玻璃橱柜,他决定把所有的奖品都放进去。所有奖品可分为两类:奖杯和奖牌。冠军比松拥有 a1 个一等奖奖杯、a2 个二等奖奖杯和 a3 个三等奖奖杯;此外,他还拥有 b1 枚一等奖奖牌、b2 枚二等奖奖牌和 b3 枚三等奖奖牌。
显然,橱柜中的奖品必须看起来美观,因此冠军比松决定遵循以下规则:
- 任何一层架子上不能同时放置奖杯和奖牌;
- 任何一层架子上最多只能放五个奖杯;
- 任何一层架子上最多只能放十枚奖牌。
请帮助冠军比松判断:能否将所有奖品全部放入橱柜中,且满足上述所有条件?
输入格式
The first line contains integers _a_1, _a_2 and _a_3 (0 ≤ _a_1, _a_2, _a_3 ≤ 100). The second line contains integers _b_1, _b_2 and _b_3 (0 ≤ _b_1, _b_2, _b_3 ≤ 100). The third line contains integer n (1 ≤ n ≤ 100).
The numbers in the lines are separated by single spaces.
第一行包含整数 a1、a2 和 a3(0 ≤ a1, a2, a3 ≤ 100)。
第二行包含整数 b1、b2 和 b3(0 ≤ b1, b2, b3 ≤ 100)。
第三行包含整数 n(1 ≤ n ≤ 100)。
每行中的数字以单个空格分隔。
输出格式
Print "YES" (without the quotes) if all the rewards can be put on the shelves in the described manner. Otherwise, print "NO" (without the quotes).
