For this Question: The DNA sequence is composed of a series of nucleotides abbreviated as 'A', 'C', 'G', and 'T'.
For example, "ACGAATTCCG" is a DNA sequence.
When studying DNA, it is useful to identify repeated sequences within the DNA.
Given a string s that represents a DNA sequence, return all the 10-letter long sequences (substrings) that occur more than once in a DNA molecule. You may return the answer in any order. This is a functional problem you have to complete the solve function.The first line of the input contains the string s.

<b>Constraints</b>
1 <= s. length() <= 1e5
s[i] is either 'A', 'C', 'G', or 'T'Complete the function and return the relevant strings.Sample Input:-
GGGGGGGGGGGGG

Sample Output:- 
GGGGGGGGGG, I have written this Solution Code: from collections import defaultdict
dna=input()
d=defaultdict(int)
for i in range(0,len(dna)-9):
  d[dna[i:i+10]]+=1

ans=[]
for i in d:
  if(d[i]>1):
    ans.append(i)
ans.sort()
for i in ans:
  print(i), In this Programming Language: Python, Now tell me if this Code is compilable or not?
