']' }xmsge; print $string; } " 3333333333223333322 3333333333333333333333333333333333333333333333333333333333333333333333 +333333333333333333333333333333333333333333333332333333333223333333332 +33333333333333333333333333333333323333333322333333332333333333 [33332] [8]3322[4]322 [116]32[8]322[8]32[32]32[8]22[8]2[8]3
