Alphabet Number Decoder

You are given a string of space-separated integers. Each integer corresponds to a letter in the English alphabet, where 1 stands for 'a', 2 for 'b', and so on until 26 for 'z'.

Your task is to decode the string by converting each number into its corresponding letter. Specifically, for any number \( n \) in the range \(1 \le n \le 26\), the corresponding letter is obtained by \(letter = \text{chr}(n+96)\). For example, the number 8 converts to 'h' because \(8+96=104\) and \(chr(104)\) is 'h'.

If the input string is empty, you should output an empty string.

Please note that the input will be read from standard input and the output should be printed to standard output.

inputFormat

The input consists of a single line containing a string of space-separated integers. The line may be empty.

outputFormat

Output the decoded string which is the concatenation of the corresponding letters.
