Explanation: 
First we will set with map each digital access to the collection, number of key, value for the number of occurrences of the result is: 
{a = 2, 1 = 2, 3 = 2, 5 = 2, 6 = 1} 
, but only because the map set in accordance with take the value of the key features that we want to take a number appears, we will list each value set as as a key, the value is equal to a value into the list.
