# Here the pattern is "G", String is
# "GeeksforGeeks" and position is 6
Println(findnext("G", "GeeksforGeeks", 6))
 
# Here the pattern is "e", String is
# "GeeksforGeeks" and position is 5
Println(findnext("G", "GeeksforGeeks", 5))
 
# Here the pattern is "k", String is
# "GeeksforGeeks" and position is 2
Println(findnext("G", "GeeksforGeeks", 2))
