(01)* was my first thought but then somehow I began equating (01)* with [01]* (in programming notation; aka (0+1)* in math notation), and I spent quite some time not realizing these are different. In hindsight, it doesn't make any sense.<br /><br />Oh, well. I don't understand myself.rgrighttps://www.blogger.com/profile/02991214367108471744noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-17659120585081426162020-12-09T15:30:39.476-06:002020-12-09T15:30:39.476-06:00"Why can't we have an open-book exam?&quo..."Why can't we have an open-book exam?"<br /><br />"Because then I'd have to write a question so complex no book would have the answer."Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-80823037737289202072020-12-09T15:19:57.676-06:002020-12-09T15:19:57.676-06:00He's right. perm((10)*) is the language of str...He's right. perm((10)*) is the language of strings with an equal number of 0s and 1s. The strings 0^n are distinguished by the strings 1^n.
