Teacher: In this task, you are given an input list A. You need to find all the elements of the list that are numbers and calculate their sum.
Teacher: Now, understand the problem? If you are still confused, see the following example:
['238', 'h', '92', 'U', '2799']
Solution: 3129
Reason: Here, the numbers in the input list are '238', '92' and '2799', hence their sum (238+92+2799) is 3129.

Now, solve this instance: ['h', 'p', 'z', 'M', '6067', 's', 'h', 'c', '2419', 'B', '7227', '8059', 'h', 'K', 'j', '2751', 'J', '4351']
