Need to implement git ignore functionality
*: match with 1 segment
**: match with 0 or more segments
*.txt: does not need to be supported.
bool IsMatch(string filePath, string pattern)
1.filePath: "/ab/cd/ef/gh/ij/lm.txt"
pattern: "/ab/*/ef/**/lm.txt"
-->return true
Reason-->{
ab cd ef gh ij lm.txt
ab * ef ** lm.txt
}
2.filePath: "/ab/cd/ef/gh/ij/lm.txt"
pattern: "/ab/*/ef/**/pq/lm.txt"
-->false
3.filePath: "/ab/cd/ef/gh/ij/lm.txt/ddd/dc/lm.txt/ddd/dd"
pattern: "/ab/*/ef/**/lm.txt/ddd/dd"
--> true
boolean isMatch(String filePath, String pattern){
}
