In this task, we needed to find a large enough number of distinct words. How can we, for instance, generate $50000$ different words? Fortunately, there are many ways to do this.

One solution is to notice that it is very easy to output a sufficient number of different numbers. For example, we can output them sequentially: $1,2,3,\dots$, and it is possible to transform these numbers to words by, for example, transforming digits to letters using the key $0$ → a, $1$ → b, $2$ → c, and so on. For instance, the number $451$ is transformed to the word efb. If we use this way to transform every integer from $1$ to $B$, all given words are distinct because the initial numbers are also distinct.

If we hadn't thought of this solution, we could have output $B$ words by randomly choosing letters per word (using a function such as rand() in C/C++ or the module random in Python). This approach will be valid because all given words will be distinct with a high probability.
