Replace Digits with Words

You are given a string consisting of lowercase letters and digits. Your task is to replace each digit in the string with its corresponding English word. The digit-to-word mapping is as follows:

• $$0 \to \texttt{zero}$$
• $$1 \to \texttt{one}$$
• $$2 \to \texttt{two}$$
• $$3 \to \texttt{three}$$
• $$4 \to \texttt{four}$$
• $$5 \to \texttt{five}$$
• $$6 \to \texttt{six}$$
• $$7 \to \texttt{seven}$$
• $$8 \to \texttt{eight}$$
• $$9 \to \texttt{nine}$$

For example, if the input is "a1b2c3", then the output should be "aonebtwocthree".

inputFormat

The input consists of a single line containing the string. The string may contain lowercase letters and digits. It can also be an empty string.
