prev  |  next  |  chance

Modify and return the given map as follows: if the key "a" has a value, set the key "b" to have that same value. In all cases remove the key "c", leaving the rest of the map unchanged.

mapShare({"a": "aaa", "b": "bbb", "c": "ccc"}) → {"a": "aaa", "b": "aaa"}
mapShare({"b": "xyz", "c": "ccc"}) → {"b": "xyz"}
mapShare({"a": "aaa", "c": "meh", "d": "hi"}) → {"a": "aaa", "b": "aaa", "d": "hi"}

...Save, Compile, Run (ctrl-enter)
