题目描述
Farmer John's N cows (1≤N≤100) are standing in a line. The ith cow from the left has label i, for each 1≤i≤N.
Farmer John has come up with a new morning exercise routine for the cows. He tells them to repeat the following two-step process exactly K (1≤K≤109) times:
The sequence of cows currently in positions A1…A2 from the left reverse their order (1≤A1<A2≤N).
Then, the sequence of cows currently in positions B1…B2 from the left reverse their order (1≤B1<B2≤N).
After the cows have repeated this process exactly K times, please output the label of the ith cow from the left for each 1≤i≤N.
SCORING:
Test cases 2-3 satisfy K≤100.
Test cases 4-13 satisfy no additional constraints.
INPUT FORMAT :
The first line of input contains N and K. The second line contains A1 and A2, and the third contains B1 and B2.
OUTPUT FORMAT:
On the ith line of output, print the label of the ith cow from the left at the end of the exercise routine.
Initially, the order of the cows is [1,2,3,4,5,6,7] from left to right. After the first step of the process, the order is [1,5,4,3,2,6,7]. After the second step of the process, the order is [1,5,7,6,2,3,4]. Repeating both steps a second time yields the output of the sample.
Farmer John 的 N头奶牛( 1≤N≤100)站成一排。对于每一个 1≤i≤N,从左往右数第 i 头奶牛的编号为 i。
Farmer John 想到了一个新的奶牛晨练方案。他让她们重复以下包含两个步骤的过程 K( 1≤K≤109)次:
1.当前从左往右数在位置 A1…A2 的奶牛序列反转她们的顺序( 1≤A1<A2≤N)。
2.然后,在当前从左往右数在位置 B1…B2 的奶牛序列反转她们的顺序( 1≤B1<B2≤N)。
当奶牛们重复这一过程 K 次后,请对每一个 1≤i≤N 输出从左往右数第 i 头奶牛的编号。
输入格式
输入的第一行包含 N 和 K。第二行包含 A1 和 A2,第三行包含 B1 和 B2。
输出格式
在第i行输出晨练结束时从左往右数第i头奶牛的编号。
输入输出样例
输入#1
7 2 2 5 3 7
输出#1
1 2 4 3 5 7 6
说明/提示
样例说明:初始时,奶牛们的顺序从左往右为 [1,2,3,4,5,6,7]。在这一过程的第一步过后,顺序变为 [1,5,4,3,2,6,7]。在这一过程的第二步过后,顺序变为 [1,5,7,6,2,3,4]。再重复这两个步骤各一次可以得到样例的输出。
测试点性质:
测试点 2-3 满足 K≤100。
测试点 4-13 没有额外限制。
