Find Consecutive Digit Segments

Find Consecutive Digit Segments

Given a string, your task is to extract and print all segments that contain at least three consecutive digits. A segment is defined as a contiguous sequence of decimal digits. If the input string does not contain any segment with three or more consecutive digits, print -1.

Input Example: hello1234world5670abc890123
Output Example: 1234 5670 890123

Use regular expressions or similar techniques available in your programming language to solve this problem efficiently.

inputFormat

The input consists of a single line containing the string.

outputFormat

If segments with three or more consecutive digits exist, output them in the order they appear in the string separated by a single space. Otherwise, output -1.
