凯撒加密是一种经典加密算法，把文本中的每个英文字母替换为字母表中后面第k个字母。该加密算法的抗攻击...
If you havetwo or more letters with the same frequency, then return the letter which comes first in the latin alphabet. For example -- "one" contains "o", "n", "e" only once for each, thus we choose "e". Input:A text for analysis as a string (unicode for py2.7). Output:The ...
14. Check if a String is a PangramWrite a Python function to check whether a string is a pangram or not.Note : Pangrams are words or sentences containing every letter of the alphabet at least once. For example : "The quick brown fox jumps over the lazy dog" Sample Solution:...

This cipher rotates the letters of the alphabet (A to Z). The encoding replaces each letter with the 1st to 25th next letter in the alphabet (wrapping Z to A). So key 2 encrypts "HI" to "JK", but key 20 encrypts "HI" to "BC". This simple "monoalphabetic substitution cipher" ...
一个continue语句通常被放在一个if语句的块中,以便在某些条件下,在循环的开始处继续执行。让我们回到我们的代码,看看它是如何使用continue语句根据使用的密钥跳过执行的。 使用continue跳过代码 在源代码中,第 35 行使用cryptomath模块中的gcd()函数来确定密钥 A 对于符号集大小是否互质: ...
A Foolish Consistency is the Hobgoblin of Little Minds (意译)不要硬套本文的编码风格,不动脑子去保持一致性是愚蠢的 One of Guido’s key insights is that code is read much more often than it is written. The guidelines provided here are intended to improve the readability of code and make it...
A pangram is a sentence where every letter of the English alphabet appears at least once. Given a string sentence containing only lowercase English letters, return true if sentence is a pangram, or false otherwise. Example 1: Input: sentence = "thequickbrownfoxjumpsoverthelazydog" Output: tr...
