Extending GolezTrol's answer you can use regular expressions to significantly reduce the number of recursive queries you do: REGEXP_COUNT() returns the number of times the pattern matches, in this case the number of times R exists in SSSRNNSRSSR. Interesting challenge. for i in x: You can use this operator to search for characters with specific formatting such as uppercase characters, or you can search for special characters such as digits or punctuation characters. x=list(dict.fromkeys(str)) Match the preceding expression only when it occurs at the end of a line. If current character is not present in hash map, Then push this character along with its Index. The pipelined table function is a fair bit slower, though it would be interesting to see how it performs over large strings with lots of matches. Out of t If the character repeats, then if the index where it repeated is less than the index of the previously repeated character then store this character and its index where it repeated.In last print that stored character.
