Infinite recursion can occur if recursion does not reduce the problem in a manner that allows it to eventually converge into the base case. Every recursive function must have a base case or a stopping condition. Every recursive call reduces the original problem, bringing it increasingly closer to a base case until it becomes that case. 2 1 point To create a map where strings are the values an map map1 ars are the keys you would use: map map1 map map1 map map1 3 1 point Given this declaration: map things; Which of the following is correct? things[12, "foo"); things[12] ="foo"; things["foo"] =12; things["foo", 12]
