Nikita had a word consisting of exactly $$$3$$$ lowercase Latin letters. The letters in the Latin alphabet are numbered from $$$1$$$ to $$$26$$$, where the letter "a" has the index $$$1$$$, and the letter "z" has the index $$$26$$$.

He encoded this word as the sum of the positions of all the characters in the alphabet. For example, the word "cat" he would encode as the integer $$$3 + 1 + 20 = 24$$$, because the letter "c" has the index $$$3$$$ in the alphabet, the letter "a" has the index $$$1$$$, and the letter "t" has the index $$$20$$$.

However, this encoding turned out to be ambiguous! For example, when encoding the word "ava", the integer $$$1 + 22 + 1 = 24$$$ is also obtained.

Determine the lexicographically smallest word of $$$3$$$ letters that could have been encoded.

A string $$$a$$$ is lexicographically smaller than a string $$$b$$$ if and only if one of the following holds:

• $$$a$$$ is a prefix of $$$b$$$, but $$$a \ne b$$$;
• in the first position where $$$a$$$ and $$$b$$$ differ, the string $$$a$$$ has a letter that appears earlier in the alphabet than the corresponding letter in $$$b$$$.
