||For this SRM's 500 ptr, the special integers are given as a vector of strings. I'm wondering:
- The first thing most coders do is to concatenate the strings together to get a single long string. A lot of previous problems' arguments are given in this manner. Why is the string not given as a single one? After all, it is no more than 2500 characters long and string concatenation is not part of the intended algorithm.
- For this problem, special integers fit in the range of 32-bit integers. Why bother give them as strings?
