* Given a nested list of integers, returns the sum of all integers in the list weighted by their depth

* For example, given the list {{1,1},2,{1,1}} the function should return 10 (four 1's at depth 2, one 2 at depth 1)

* Given the list {1,{4,{6}}} the function should return 27 (one 1 at depth 1, one 4 at depth 2, one 6 at depth2)

I am not able to understand this question fully. Can someone please explain, what happens if i have the setup like below :

{

{0,1,0},

{1,0,0},

{0,0,0}

}

Why is influncer = 2 here, i understand {2,0} {2,1} are 0's. BUT shouldnt {0,2} and {1,2} be equal to 1, meaning 0,1 are following2, but 2 is not following anyone ... ?
