P12_CompilerVersion.py

# You are converting an old code for a new version of the compiler.
#
# In the old code we have used "->" for pointers. But now we have to replace each "->" with a ".". But this
# replacement shouldn't be done inside commments. A comment is a string that starts with "//" and terminates
# at the end of the line.
#
# Input:
#
# At max.
# 2000
# 2000 lines of code.
#
# Each line of code consists of at maximum
# 60
# 60 characters.
#
# Output:
#
# New code with required changes.
#
# SAMPLE INPUT
# int t; //variable t
# t->a=0;  //t->a does something
# return 0;
#
# SAMPLE OUTPUT
# int t; //variable t
# t.a=0;  //t->a does something
# return 0;
