PreviousSubmit
Solution
The quantifier that matches any string that contains at least one 'n' is 'n+'.
Here's why:
-
'n+' : This quantifier matches any string that contains at least one 'n'. The '+' means one or more of the preceding element.
-
'n*n' : This quantifier matches any string that contains zero or more 'n's followed by an 'n'.
-
'?n' : This quantifier matches any string that contains zero or one 'n'. The '?' means zero or one of the preceding element.
-
'n{2,3}' : This quantifier matches any string that contains two to three 'n's. The '{2,3}' means between two and three of the preceding element.
