Hello all,
Was just attempting this question for practice and have used Python3. I am
repetitively getting WA and I am not able to find any specific case that I
might have missed.
Here's the code:
T = int(input())
t = 1
cas = ["P","R","S"]
while(t <= T):
res = ""
A = int(input())
l = []
for i in range(A):
l.append(input())
pos = 0
while(len(l) > 0):
# print(l)
al = []
for i in l:
if(i[pos%len(i)] not in al):
al.append(i[pos%len(i)])
if(len(al) == 1):
res += cas[(cas.index(al[0])-1)%3]
l.clear()
elif(len(al) == 3):
res = "IMPOSSIBLE"
l.clear()
else:
al = sorted(al)
if(al[1] == "S" and al[0] == "P"):
res += "S"
else:
res += al[0]
l = list(filter(lambda x: x[pos%len(x)] != al[1],l))
pos += 1
print("Case #{}: {}".format(t, res))
# print("Case #",t,": ",res,sep="")
t += 1
would be great if someone could help me out.
Thanks in advance!
