+# Memoize II
+[LeetCode Problem]https://leetcode.com/problems/memoize-ii/
 
+Given a function fn, return a memoized version of that function.
+
+A memoized function is a function that will never be called twice with the same inputs. Instead it will return a cached value.
+
+fn can be any function and there are no constraints on what type of values it accepts. Inputs are considered identical if they are === to each other.
+
+## Example 1:
+```javascript
+Input: 
+getInputs = () => [[2,2],[2,2],[1,2]]
+fn = function (a, b) { return a + b; }
+Output: [{"val":4,"calls":1},{"val":4,"calls":1},{"val":3,"calls":2}]
+Explanation:
+const inputs = getInputs();
+const memoized = memoize(fn);
+for (const arr of inputs) {
+  memoized(...arr);
+}
+
+For the inputs of (2, 2): 2 + 2 = 4, and it required a call to fn().
+For the inputs of (2, 2): 2 + 2 = 4, but those inputs were seen before so no call to fn() was required.
+For the inputs of (1, 2): 1 + 2 = 3, and it required another call to fn() for a total of 2.
