A baseball player's batting average is calculated as the number of hits divided by the official number of at-bats. In calculating official at-bats, walks, sacrifices, and occasions when hit by the pitch are not counted. Write a program that takes an input file containing player numbers and batting records. Trips to the plate are coded in the batting record as follows: H--hit, O--out, W--walk, S--sacrifice, P--hit by pitch. The program should calculate each player's batting average.

4 OSOHHHWWOHOHOOO

7 WPOHOOHWOHHOWOO

Player 12's record: HOOOWSHHOOHPWWHO

Player 12's batting average: 0.455

Player 4's record: OSOHHHWWOHOHOOO

Player 4's batting average: 0.417

Player 7's record: WPOHOOHWOHHOWOO

Player 7's batting average: 0.364
