Pattern 2 - The length of this pattern is exactly 11 and can start with a zero. These consist of only integers. Ex: '01234567890'
Pattern 3 - The length of this pattern is exactly 11 and cannot start with a zero. There is one space after the 5th number and all other characters are numbers. Ex: '12345 67890'
Pattern 4 - The length of this pattern is exactly 12 and can start with a zero. There is one space after the 6th number and all other characters are numbers. Ex: '012345 67890'
Note - The example pattern example provided is for representation only. The actual set of numbers in my string can be anything. Example: '2345653340' or '034945 85730' or '000000 00000' or '09876543210'.";
