Given an array nums of integers, return how many of them contain an even number of digits.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [12,345,2,6,7896]\nOutput: 2\nExplanation: \n12 contains 2 digits (even number of digits). \n345 contains 3 digits (odd number of digits). \n2 contains 1 digit (odd number of digits). \n6 contains 1 digit (odd number of digits). \n7896 contains 4 digits (even number of digits). \nTherefore only 12 and 7896 contain an even number of digits.\n
\n\n

Example 2:

\n\n
\nInput: nums = [555,901,482,1771]\nOutput: 1 \nExplanation: \nOnly 1771 contains an even number of digits.\n
