Design_Problems_leetcode in C++

LRU cache implemented in C++, fast enough
LFU cache implemented in C++, unoptimized, no memory leak
Design In Memory File System, efficient, not tested against all test cases
Design Compressed String Iterator, efficient, not tested as locked
443. String Compression(reverse task) code:

Well, Do not fear recursion( better call it backtracking ). Because of this cheat_sheet
