Once COUNTER reaches 1000000, you have all of the values stored in the incessant stream of ICMP requests, and VALUE now contains the maximum integer. Pick some threshold T >> 1000000. Set COUNTER to zero. Every time you receive an ICMP pack...
Why should I use a pointer rather than the object itself?
...le. You cannot change the size of arrays either. For example:
char buffer[100];
std::cin >> buffer;

What would cause an algorithm to have O(log n) complexity?
...64, 10*log(64) = 60, which is less than the runtime of 64. You can pick c=100, or 1000, or a gazillion, and you'll still be able to find some N that violates that requirement. In other words, there is no N_0.
If we do a binary search, though, we pick the middle element, and make a comparison. Th...
