Everyone was surprised that the clues to the elevator's password were found so easily.
"Even if we know it's 3578, it's still no good if we don't know the order of the numbers, right?" Natasha said.
Bai Youwei replied casually, "Just try them one by one~"
"Try them one by one?" Natasha was astonished, "Do you know how many permutations there are for a four-digit number?"
Bai Youwei: "Of course, 24, we can quickly test them all."
Natasha: "..."
While she was still stunned, Bai Youwei had already started tapping rapidly on the electronic screen, quickly testing the passwords!
Natasha was plunged into deep self-doubt.
She turned to Ada and asked, "Is it really 24?"
Ada was also dumbfounded, "Seems... right..."
After pondering for a moment, Shen Mo said gravely: "The combination for a four-digit password should exceed ten thousand, but if we are sure of the specific digits and the digits do not repeat, there indeed are only 24 permutations."
