# Write a function `replace_dashes` that takes a 
# dictionnary as input and rename the keys so that
# every '_' is replaced by '-'.
# Your function should not change the values, for 
# example, if the input is:
# {
#   "key_1": "value_1",
#   "key_2": "value_2",
#   "key_3": {
#     "key_4": "value_4"
#   }
# }
# its output should be:
# {
#   "key-1": "value_1",
#   "key-2": "value_2",
#   "key-3": {
#     "key-4": "value_4"
#   }
# }

print(replace_dashes({
   "key-1": "value_1",
   "key-2": "value_2",
   "key-3": {
     "key-4": "value_4"
   }
}))
