I am a beginner in Clojure.
I have a list of maps:
(def p '({:a 1 :b 2 :c 4}, {:a 2 :b 3 :c 5}, {:a 3 :b 4 :c 6}))
How do I add up all the :b values in the map? Result should be 9
(=2+3+4)
I know I should be using one of the higher level functions like apply,
reduce and combine it with a custom filter function. But not sure how to
write it.
