Description
Nastya and Rice
题意翻译
有$n$个范围为$[a-b,a+b]$的数,判断他们的和是否可能在$[c-d,c+d]$范围中。 输入有多组数据($1 \le T \le 1000$),保证: - $1 \le n \le 1000$ - $0 \le b < a \le 1000 $ - $0 \le d < c \le 1000$ 输入格式: - 第一行为数据组数$T$。 - 接下来每行五个整数,$n,a,b,c,d$。 输出格式: - 如果所有数的和可能在$[c-d,c+d]$范围中,输出`Yes`,否则输出`No`。题目描述
Nastya just made a huge mistake and dropped a whole package of rice on the floor. Mom will come soon. If she sees this, then Nastya will be punished. In total, Nastya dropped $ n $ grains. Nastya read that each grain weighs some integer number of grams from $ a - b $ to $ a + b $ , inclusive (numbers $ a $ and $ b $ are known), and the whole package of $ n $ grains weighs from $ c - d $ to $ c + d $ grams, inclusive (numbers $ c $ and $ d $ are known). The weight of the package is the sum of the weights of all $ n $ grains in it. Help Nastya understand if this information can be correct. In other words, check whether each grain can have such a mass that the $ i $ -th grain weighs some integer number $ x_i $ $ (a - b \leq x_i \leq a + b) $ , and in total they weigh from $ c - d $ to $ c + d $ , inclusive ( $ c - d \leq \sum\limits_{i=1}^{n}{x_i} \leq c + d $ ).输入输出格式
输入格式
The input consists of multiple test cases. The first line contains a single integer $ t $ $ (1 \leq t \leq 1000) $ — the number of test cases. The next $ t $ lines contain descriptions of the test cases, each line contains $ 5 $ integers: $ n $ $ (1 \leq n \leq 1000) $ — the number of grains that Nastya counted and $ a, b, c, d $ $ (0 \leq b < a \leq 1000, 0 \leq d < c \leq 1000) $ — numbers that determine the possible weight of one grain of rice (from $ a - b $ to $ a + b $ ) and the possible total weight of the package (from $ c - d $ to $ c + d $ ).
输出格式
For each test case given in the input print "Yes", if the information about the weights is not inconsistent, and print "No" if $ n $ grains with masses from $ a - b $ to $ a + b $ cannot make a package with a total mass from $ c - d $ to $ c + d $ .
