0917. Largest pair sum in array Given a sequence of numbers, find the largest pair sum in the sequence. For example [10, 14, 2, 23, 19] --> 42 (= 23 + 19) [99, 2, 2, 23, 19] --> 122 (= 99 + 23) Input sequence contains minimum two elements and every element is an integer. Solution: def largest_pair_sum(numbers): return sum(sorted(numbers)[-2:]) 2022. 9. 17.
Row Weights Scenario Several people are standing in a row divided into two teams. The first person goes into team 1, the second goes into team 2, the third goes into team 1, and so on.

Consecutive strings You are given an array(list) strarr of strings and an integer k. Your task is to return the first longest string consisting of k consecutive strings taken in the array. Examples: strarr = ["tree", "foling", "trashy", "blue", "abcdef", "uvwxyz"], k = 2 Concatenate the consecutive strings of strarr by 2, we get: treefoling (length 10) concatenation of strarr[0] and strarr[1] folingtrashy (" 12) co.. 2022. 8. 13.
Maximum subarray sum The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers: max_sequence([-2, 1, -3, 4, -1, 2, 1, -5, 4]) # should be 6: [4, -1, 2, 1] Easy case is when the list is made up of only positive numbers and the maximum sum is the sum of the whole array. If the list is made up of only negative numbers, return 0 instead. Empty list i.. 2022. 8. 12.
Simple Fun #176: Reverse Letter Task Given a string str, reverse it and omit all non-alphabetic characters. Example For str = "krishan", the output should be "nahsirk". For str = "ultr53o?n", the output should be "nortlu". Input/Output [input] string str A string consists of lowercase latin letters, digits and symbols.
