n, ck = map(int, input().split())
lis = []
co = 0
for _ in range(ck):
cl = input()
xt = cl[len(cl)-1]
if xt.isdigit():
if xt in lis:
lis.remove(xt)
else:
lis.append(xt)
else:
lis.clear()
print(len(lis))
please this and check what’s going wrong
Put link of your submission.
Also IDK Python i will try to code in c++ or java.

cl=input()
Here If input given line is
CLICK 43,
Then cl=“CLICK 43”
and not cl=[“CLICK”, “43”]
so in, xt=cl[len(cl)-1] it will store ‘3’ in xt and not “43”
So, instead of cl=input()
Write cl=list(input().split())
