+Find the number of even digits in the given integer.
+
+**Example**
+
+* For `n = 1010`, the output should be `numberOfEvenDigits(n) = 2`.
+* For `n = 123`, the output should be `numberOfEvenDigits(n) = 1`.

+Map the given integer to a month.
+
+**Example:**
+
+* For `mo = 1`, the output should be `getMonthName(mo) = "Jan"`,
+* For `mo = 0`, the output should be `getMonthName(mo) = "invalid month"`.
+
+**Input/Output**
+
+* [time limit] 4000ms (py)
+* [input] integer mo (A non-negative integer).
+* **Constraints:** `0 ≤ mo ≤ 15`.
+* **[output] string**
+
+A `3`-letter abbreviation of month number `mo` or `"invalid month"` if the month doesn't exist.
+
+Here are abbreviations of all months:
+
+**My Solution:**
+
+```python
+def getMonthName(mo):
+    months = {
+        1: "Jan", 2: "Feb", 3: "Mar", 4:"Apr", 
+        5: "May", 6: "Jun", 7: "Jul", 8:"Aug",

+    }
+    if mo in months.keys():
+        return months.get(mo)
+    return "invalid month"
+```
+
+**Result Tests**:
+
+```python
+>>> getMonthName(1)
+"Jan"
+>>> getMonthName(0)
+"invalid month"
+>>>
+```
