[Lemo Puzzle] Two array, boxes and lemos stand for size of boxes and size of lemos. Every lemo can be put into a box which has equal or bigger size. Pick a start point i from lemos array, find a possible box and repeat this action for i+1, i+2. All lemos in boxes should keep their original orders. What is the longest sequence of lemos in boxes. …
#include <iostream>
int boxes[10] = {5, 3, 2, 7, 10, 9, 1, 6, 4, 8};
int lemons[10] = {2, 6, 7, 1, 10, 5, 4, 3, 9, 8};
