1. Plain Strings : foot* - Self explanatory
2. Anchors : k$ - Ends with letter 'k'
3. Ranges : ^[a-f]*$ - All alphabets are in range a-f
4. Backrefs : (...).*\1 - 4 alphabets are repeated somewhere later in string
5. abba : ^(?!.*(.)(.)\2\1) - 2 alphabets followed by reverse, capture backreference and play them in reverse. Answer is those strings which do not match this pattern, we do that by negative lookahead assertion
6. A man, a plan : ^(.)(.).*\2\1$ - Similar to above
7. Prime : `` - TODO
8. Four : (.).\1.\1.\1 - a letter is repeated 4 times in string somewhere; capture backreference and play it over
9. Order : ^[^o].....?$ or ^[^o].{4,5}$ - string has 5-6 letters; one string which starts with 'o' protests, so add negation for that and subtract one from range. Simple
10. Triples : `` - TODO
