CSES - Binary Subsequences. Your task is to find a minimum length bit string that has exactly n distinct subsequences. For example, a correct solution for n = ... |
Therefore, we have a bijection the set of binary strings with exactly n subsequences (including the empty one) and the set of binary strings generated by trace ... |

All strings of length at most k appear as a subsequence, so the answer has to be at least k+1. But, we can actually do k+1. Thus, the minimum is exactly k+1. |
#define up(i,a,b) for (int i = (int)a; i <= (int)b; i++). #define down(i,a,b) for (int i = (int)a; i >= (int)b; i--). #define ep emplace_back. |
