# As not mentioned I am assuming you want the cide in python language 
# just because the given code syntax just look like python
# If you want in any other language just folluw the same approach
# That will provide you the same result

# search for track by name.

# Returns the index of the track or -1 if not found

def search_for_track_name(tracks, search_string):
    # Using while loop
    # just by traversing the tracks array if  search_string found
    # return Index and chnge flag to 1 and print found and if after traversing full array
    # take a variable flag if it is 0 return not found
    flag = 0
    i = 0
    found_index=0
    while(tracks.length()--):
        if (tracks[i] == search_string):
            flag = 1
            found_index = i
            break;
        i += 1 
    if flag == 0:
        return - 1;
    return found_index

end

def main():
    music_file = File.new("album.txt", "r")
    tracks = read_tracks(music_file)
    music_file.close()

    #  taking the input of search string
    search_string = read_string("Enter the track name you wish to find: ")

    #  calling function to search string
    index = search_for_track_name(tracks, search_string)
    if index > -1
        puts "Found " + tracks[index].name + " at " + index.to_s()
    else
