By setting the total number of elements in the list to the second argument, random.sample() returns a new list with all elements randomly shuffled. By default, current system time is used as a seed value. Given two strings S1 and S2 of equal length, the task is to determine if S2 is a scrambled form of S1.Scrambled string:Given string str, we can represent it as a binary tree by partitioning it into two non-empty substrings recursively.Note: Scrambled string is not same as an AnagramBelow is one possible representation of str = coder: To scramble the string, we may choose any non-leaf node and swap its two children. of the message, and interleaving them.

Python string.strip () method removes the white-spaces from the front and back end of a particular string. You can read the full documentation here. Strings in python are surrounded by either single quotation marks, or double quotation marks. For example, str1 = "Hello, world!" str2 = "I love Python." random.sample() returns a list even when a string or tuple is specified to the first argument, so it is necessary to convert it to a string or tuple. Python strings are written between single quote marks like 'Hello' or alternately they can be written in double quote marks like "There". Total 37 unscrambled words are categorized as follows; And if it happens that you don't understand why "n<4 --> True automatically" just like me at first, here's why: suppose only 3 letters left, a, b, and c. All possible permutations of these 3 letters are scrambled string of each other. I don't know what translation was otherwise saved. By default, the step is 1 but in the following example, the step size is 2. string = "welcome to freecodecamp" print (string [::2]) The output will be 'wloet fecdcm'. You can trim a string in Python using three built-in functions: strip () , lstrip (), rstrip () methods respectively. The steps involved are: There is a three-line version to this problem: import random as r Can the Spiritual Weapon spell be used as cover?
