# one of the first string's permutations is the substring of the second string. # The input strings only contain lower case letters. # The length of both given strings is in range [1, 10,000].

Following a BFS approach, we will consider one number at a time: Given a string, find all of its permutations preserving the character sequence but changing case. This problem follows the Subsets ...

One of the most striking consequences of this quantum space-time, as predicted by string theory, is that it naturally leads to cosmic acceleration. Moreover, the researchers found that the rate at ...
