Everool has a binary string ss of length 2n2n. Note that a binary string is a string consisting of only characters 00 and 11. He wants to partition ss into two disjoint equal subsequences. He needs your help to do it. You are allowed to do the following operation exactly once. You ...
The Number of Distinct Subsequences of a Random Binary String We determine the average number of distinct subsequences in a random binary string, and derive an estimate for the average number of distinct subsequences of a particular length. MJ Collins - 《Mathematics》 被引量: 2发表: 2013年 ...
