I would like to know if we can handle specific input like the following examples using pattern:
[1] or
[1,2]
so basically brackets with a number or if there are more numbers then only comma allowed as a separator.
Tried [(\d+(\s*,?))+] as stated below but it doesn’t work.
>Solution :
This would do it:
^\[\d+(?:,\d+)*\]$
^– start line anchor\[– open literal square bracket\d+– one or more digits(?:– open non-capturing group,\d+– comma followed by one or more digits
)– close non-capturing group*– match pattern inside non-capturing group zero or more times\]– close literal square bracket$– end line anchor
