Codeforces Round #455 (Div. 2)
C. Python Indentation
Test instructions: In Python, given n for loops or statements, ' F ' must have a statement. Combine the python indentation into a legitimate program and ask how many possible scenarios.

Question: Find the minimum cyclic section of a string.
Analysis: brute force, String. If the data volume is small, use the enumeration method directly.
Enumerate the length of the cyclic section, match and judge, find the first group of solutions to be the minimum.
Note: (⊙ _ ⊙ ).

A character string is said to have period K if it can be formed by concatenating one one or more repetitions of another of length K. For example, the string "ABCABCABCABC" has period 3, since it is formed by 4 repetitions of the string "abc". It also has periods 6 (two repetitions of "ABCABC") and (one repetition of "abc
int compare (Size_type index, size_type length, const basic_string str, Size_type index2,size_type length2);
Compare your own substrings and str substrings, where index2 and length2 reference str,index and length refer to themselves

different results. We add a colon to the left and right of each field to clearly indicate the width of the field.:%s:: Hello, World::%10s:: Hello, World::%.10s:: Hello, wor::%-10s:: Hello, World::%.15s:: Hello, World::%-15s:: Hello, World::%15.10s:: Hello, wor::%-15.10s:: Hello, wor:-(minus sign): Causes the output to be left-aligned in the field width.

timeMeaning one. Inherit the method of the base class and make your own changes or extensions (code reuse)Meaning two. Declares that a subclass is compatible with a base class, defines an interface class, inherits the interface class, and implements the methods defined in the interfaceThe greatest benefit of inheritance is the reduction of code reuseExample:Class Hero: #父类 def __init__ (self,nickname,aggressivity=58,life_value=455,): self.n
