Excellent logic. Super easy. Didn't think this way. Thanks a lot!

Hi, nice approach. Just a minor enhancement. We don't need to build minimum size string. We only require to return its length. So, we can just return size of HashSet instead of building string and returning its length.

TS:

function minStr(str: string) {
const res: {[key: string]: number} = {}

for(let i = 0; i < str.length; i++) {
res[str[i]] = i
}

return Object.keys(res).length;
}

FYI doesn't match your thumbnail. Also can you keep the episode number local to the playlist and keep it out to the title? For example within Hashtable 2716 isn't Episode 142 it's 23 ;-)
