Algorithm101 Sort array by string length Description: Write a function that takes an array of strings as an argument and returns a sorted array containing the same strings, ordered from shortest to longest. For example, if this array were passed as an argument: ["Telescopes", "Glasses", "Eyes", "Monocles"] Your function would return the following array: ["Eyes", "Glasses", "Monocles", "Telescopes"] All of the strings in the array passe.. 2022. 4. 29. Sum of odd numbers Description: Given the triangle of consecutive odd numbers: 1 3 5 7 9 11 13 15 17 19 21 23 25 27 29 ... Calculate the sum of the numbers in the nth row of this triangle (starting at index 1) e.g.: (Input --> Output) 1 --> 1 2 --> 3 + 5 = 8 Solution: 1. Add up all 'n' numbers. 2. Find the odd number by the added number. 3. It returns after adding 'n' odd numbers from the last. def row_sum_odd_num.. 2022. 4. 28. Mumbling Description: This time no story, no theory. The examples below show you how to write function accum: Examples: accum("abcd") -> "A-Bb-Ccc-Dddd" accum("RqaEzty") -> "R-Qq-Aaa-Eeee-Zzzzz-Tttttt-Yyyyyyy" accum("cwAt") -> "C-Ww-Aaa-Tttt" The parameter of accum is a string which includes only letters from a..z and A..Z. Solution: 1. Extract each character from a string with an index. 2. Characters ar.. 2022. 4. 27. Two to One Description: Take 2 strings s1 and s2 including only letters from ato z. Return a new sorted string, the longest possible, containing distinct letters - each taken only once - coming from s1 or s2. Examples: a = "xyaabbbccccdefww" b = "xxxxyyyyabklmopq" longest(a, b) -> "abcdefklmopqwxy" a = "abcdefghijklmnopqrstuvwxyz" longest(a, a) -> "abcdefghijklmnopqrstuvwxyz" Solution: 1. Concatenate strin.. 2022. 4. 26. Apparently-Modifying Strings Description: For every string, after every occurrence of 'and' and/or 'but', insert the substring 'apparently' directly after the occurrence(s). If input does not contain 'and' or 'but', return the same string. If a blank string, return ''. If substring 'apparently' is already directly after an 'and' and/or 'but', do not add another.
