Yet another way to solve it:
*user=> x[[1 0.5] [1 0.7] [2 1.0] [3 0.1] [3 0.1]]user=> (group-by first
x){1 [[1 0.5] [1 0.7]], 2 [[2 1.0]], 3 [[3 0.1] [3 0.1]]}user=> (map
#(vector (first %) (second %)) (group-by first x))([1 [[1 0.5] [1 0.7]]] [2
[[2 1.0]]] [3 [[3 0.1] [3 0.1]]])user=> (map #(vector (first %) (reduce +
(map second (second %)))) (group-by first x))([1 1.2] [2 1.0] [3 0.2])*
All the best,
Emrehan
