how do i solve this
i've been racking my brain over it for atleast half an hour now but can't seem to get it

#

here's the question

untold mango
#

well ...... ur using an n^2 (n-squared) algorythm
and ur probably recounting the same bird ID's over and over

i mean if u have
1,3,1,1,3,1,2 then for i=0 u count the frequency of id=1 and at i=2 u count the same id again and at i=3 u count the same id AGAIN

....also, if the highest seen ID only appears in the 2nd half of the array u wont ever count it so thats ....... not good, ur lucky the tests all passed

#

u can count them in O(n) (all of them) instead of O(n^2)

#

then u just need to find the highest frequency
