To allow only one space in a regex pattern, you can use the following regex expression:
1
|
^S+(sS+)?$ |
Explanation of the pattern:
- ^ : Start of the line
- S+ : Match one or more non-space characters
- (sS+)? : Match an optional space followed by one or more non-space characters. This part allows for one space in the middle of the string.
- $ : End of the line
You can use this regex pattern in your code to validate input and allow only one space in a string.
