maybe not the most elegant, but it work!

def expression_matter(a,b,c) sum = [a,b,c].sum tmp = [a,b,c].inject('*') sum = tmp if sum < tmp tmp = (a + b) * c sum = tmp if sum < tmp tmp = a + (b * c) sum = tmp if sum < tmp tmp = a * (b + c) sum = tmp if sum < tmp tmp = (a + c ) * b sum = tmp if sum < tmp sum end

pry(main)> expression_matter(5, 1, 3) => 20 pry(main)> expression_matter(3, 5, 7) => 105 pry(main)> expression_matter(5, 6, 1) => 36 pry(main)> expression_matter(1, 6, 1) => 12 pry(main)> expression_matter(2, 6, 1) => 18

Alternative Ruby version:

def expression_matter(a, b, c) [ a + b + c, a * b * c, a + b * c, (a + b) * c, a * b + c, a * (b + c) ].max end

We're a place where coders share, stay up-to-date and grow their careers.

We strive for transparency and don't collect excess data.
