## My Work

```
fin = open("hps.in", "r")
fout = open("hps.out", "w")
n = int(fin.readline())
myH = [0]
myP = [0]
myS = [0]
#Reading in inputs, and then using prefix sums to store in 3 separate lists
for i in range(n):
myIn = str(fin.readline())
myH.append(myH[-1])
myP.append(myP[-1])
myS.append(myS[-1])
if myIn == 'H':
myH[-1] += 1
if myIn == 'P':
myP[-1] += 1
if myIn == 'S':
myS[-1] += 1
maxi = 0
#Finding the max possible value
for x in range(1, len(myH)):
beforeWin = max(myH[x], myP[x], myS[x])
afterWin = max(myH[-1] - myH[x], myP[-1] - myP[x], myS[-1] - myS[x])
maxi = max(maxi, beforeWin + afterWin)
fout.write(str(maxi))
```

My code works with console, but not the grader system for some reason, and it gives out the wrong output???
