Your program is to output a sequence of 1 000 000 lowercase Latin letters. This sequence should satisfy the following restrictions:
- Every letter occurs not more than 40 000 times in the sequence;
- Every possible subsequence with two letters length occurs not more than 2 000 times;
- Every possible subsequence with three letters length occurs not more than 100 times;
For this problem no input is provided.
In a single line of the output write some sequence, which satisfies the properties described above.
