Hello,

is there a way I can check if a word has 2 the same chars after each other

I was hoping that '#groupby could help me but that one sorts

so abba the aa is found��

or do I have to use a stream for that

could I then also use that stream to check if a word contains 3 vowels ?

I ask also on the discord app but no answer for a long time

Regards,

Roelof
