In F#, write a function findMatches that takes a string and a list of tuples as arguments. Each element of the list will be a tuple consisting of a string and an int. Find all of the tuples for which the string matches the first argument and collect all of the corresponding integers. Your final result should be the collected integers sorted in ascending order. For example, if the string argument is "A" and the list is [("A",5); ("BB",6); ("AA",9); ("A",0)], your function should return the list [0;5]. You may use the List.sort function to produce your final result.

Examples in F# Interactive: > findMatches "A" [("A",5); ("BB",6); ("AA",9); ("A",0)];; val it : int list [0; 5] > findMatches "BB" [("A",5); ("BB",6); ("AA",9); ("A",0)];; val it : int list = [6] > findMatches "X" [("A",5); ("BB",6); ("AA",9); ("A",0)];; val it : int list [] > findMatches "A" [];; val it : int list Examples in F# Interactive: > findMatches "A" [("A",5); ("BB",6); ("AA",9); ("A",0)];; val it : int list [0; 5] > findMatches "BB" [("A",5); ("BB",6); ("AA",9); ("A",0)];; val it : int list = [6] > findMatches "X" [("A",5); ("BB",6); ("AA",9); ("A",0)];; val it : int list [] > findMatches "A" [];; val it : int list
