Examples "This is an example!" ==> "sihT si na !elpmaxe" "double spaces" ==> "elbuod secaps" Solutions using namespace std; int checkEmptyCount(string str, int startIndex) { int count = 0; for(int i=startIndex; i 2022. 5. 3.
Codewars - [5 kyu] Simple assembler interpreter Assembler로 들어온 문자열을 해석하여 실행하여 unordered_map로 구성된 저장된 값들을 반환하는 문제이다!

Codewars - [6 kyu] Sum consecutives You are given a list/array which contains only integers (positive and negative). Your job is to sum only the numbers that are the same and consecutive. The result should be one list. Extra credit if you solve it in one line. You can assume there is never an empty list/array and there will always be an integer. Same meaning: 1 == 1 1 != -1 #Examples: [1,4,4,4,0,4,3,3,1] # should return [1,12,0,4,.. 2022. 1. 17.
