Task: MAK Maximal orders of permutations
A permutation of n elements is a one-to-one function (injection) p: {1,2,...,n} -> {1,2,...,n}. An order of permutation p is the minimal k >= 1, such that for all i=1,2,...,n we have: , i.e. p composed with itself k times becomes identity function. For example, the order of the permutation of 3 elements
p(1)=3, p(2)=2, p(3)=1 is 2, because
p(p(1))=1, p(p(2))=2, p(p(3))=3. For a given n let us consider permutations of n-elements having the
the largest order possible. For example, the maximal order of a permutation of 5 elements
is 6. An example of a permutation of 5 elements whose order is 6 is p(1)=4, p(2)=5, p(3)=2, p(4)=1, p(5)=3.
TaskWrite a programme that:
InputThere is one positive integer d in the first line of the standard input, 1 <= d <= 10. In the following d lines there are positive integers n1, n2, ..., nd, one per line, 1 <= ni <= 10.000. OutputYour programme should write d lines to the standard output. The ith line should contain a sequence of integers separated by spaces, forming the least permutation of ni elements having the maximal order, i.e. the sequence p(1), p(2), ..., p(ni), where p denotes this permutation. ExampleFor the following input data:2 5 14the correct answer is: 2 1 4 5 3 2 3 1 5 6 7 4 9 10 11 12 13 14 8 Print friendly version |
