返回:
未排序的Prufer序列
代碼1:unrank()示例
# Python code explaining
# SymPy.Prufer.unrank()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer
# Using from
# sympy.combinatorics.prufer.Prufer.unrank()
# Creating Prufer
a = Prufer([1, 2, 3], [2, 4, 5])
# unrank value
# rank = 2
# n = 5
print ("Prufer a unrank : ", a.unrank(2, 5))
輸出:
Prufer a unrank : 125
代碼2:unrank()示例
# Python code explaining
# SymPy.Prufer.unrank()
# importing SymPy libraries
from sympy.combinatorics import Permutation, Cycle
from sympy.combinatorics.prufer import Prufer
# Using from
# sympy.combinatorics.prufer.Prufer.unrank()
# Creating Prufer
b = Prufer([1, 2, 3, 2, 4, 5], [6, 7], [8])
# unrank value
# rank = 2
# n = 5
print ("Prufer b unrank : ", b.unrank(2, 5))
輸出:
Prufer b unrank : Prufer([0, 0, 2])
