[GAP Forum] Inverse operation of ListOfDigits.

[[Muniru Asiru] [e-mail]]

Dear Forum, Dear all,

If I am given that
a:=123456;;  b:=ListOfDigits(a);
Is it possible in GAP for me to recover a given b?

Thanks.

Dear Muniru,

Yes, it's easy:

gap> Sum([0..Length(b)-1], k -> b[Length(b)-k]*10^k);
123456

Best regards, --Philippe
