 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.

+## Example 2:
+```javascript
+Input: 
+getInputs = () => [[{},{}],[{},{}],[{},{}]] 
+fn = function (a, b) { return ({...a, ...b}); }
+Output: [{"val":{},"calls":1},{"val":{},"calls":2},{"val":{},"calls":3}]
+Explanation:
+Merging two empty objects will always result in an empty object. It may seem like there should only be 1 call to fn() because of cache-hits, however none of those objects are === to each other.

+## Example 3:
+```javascript
+Input: 
+getInputs = () => { const o = {}; return [[o,o],[o,o],[o,o]]; }
+fn = function (a, b) { return ({...a, ...b}); }
+Output: [{"val":{},"calls":1},{"val":{},"calls":1},{"val":{},"calls":1}]
+Explanation:
+Merging two empty objects will always result in an empty object. The 2nd and 3rd third function calls result in a cache-hit. This is because every object passed in is identical.
