题目描述
You are given three integers n , a , and b . Determine if there exist two permutations p and q of length n , for which the following conditions hold:
- The length of the longest common prefix of p and q is a .
- The length of the longest common suffix of p and q is b .
A permutation of length n is an array containing each integer from 1 to n exactly once. For example, [2,3,1,5,4] is a permutation, but [1,2,2] is not a permutation ( 2 appears twice in the array), and [1,3,4] is also not a permutation ( n=3 but there is 4 in the array).
输入格式
Each test contains multiple test cases. The first line contains a single integer t ( 1≤t≤104 ) — the number of test cases. The description of test cases follows.
The only line of each test case contains three integers n , a , and b ( 1≤a,b≤n≤100 ).
输出格式
For each test case, if such a pair of permutations exists, output "Yes"; otherwise, output "No". You can output each letter in any case (upper or lower).
输入输出样例
输入#1
4 1 1 1 2 1 2 3 1 1 4 1 1
输出#1
Yes No No Yes
说明/提示
In the first test case, [1] and [1] form a valid pair.
In the second test case and the third case, we can show that such a pair of permutations doesn't exist.
In the fourth test case, [1,2,3,4] and [1,3,2,4] form a valid pair.
