Thursday pleasure routine: fresh Missions and useful Topics!
Hello, checkiomates🐱👤! And so we met again)
Time goes fast, it's a new Thursday and a bunch of fresh missions and topics to read! As usual you are welcome to discuss them in comments.
Ready. Steady. Go..to solve 🏁 NEW MISSIONS:
One Switch Strings by Doppelok - where you are given two strings and need to determine whether you can swap two letters in the first string to get the second string. If so - return True, if not - False. For example, the string "btry", if we swap y and t, we get "byrt".
switch_strings("btry", "byrt") == True switch_strings("boss", "boss") == True switch_strings("solid", "disel") == False
Adjacent Letters by freeman_lex - You are given a string, where all letters are of same case. This string could include adjacent letters - two the same letters together ("aa", "bb" etc). Your task in this mission is to remove both these letters. If after removing one pair a new appears - remove it as well! Each such pair should be removed from string until no one remains.
adjacent_letters("adjacent_letters") == "adjacent_lrs" adjacent_letters("") == "" adjacent_letters("aaa") == "a"
Sort Sorted Groups by freeman_lex - You are given a list of integers. Your goal is to find all sorted groups (group of numbers with distinct sorting order or single value) inside the list, sort input list by these groups and return this sorted list with groups unpacked. For example, [5, 1, 5, 0, 5] --> [[5, 1], [5, 0], ] --> [, [5, 0], [5, 1]] --> [5, 5, 0, 5, 1]. If adjacent numbers are equal, consider sorting order remains the same. If a group starts with equal numbers, seek the different number further to determine or check sorting order, or end of the list.
sorted_groups() ==  sorted_groups() ==  sorted_groups([5, 1, 5, 0, 5]) == [5, 5, 0, 5, 1]
