In Ruby 2.4+, you can calculate the sum of all numbers in an array using the Array#sum method, for example, in the following way: # Ruby 2.4+ print [1, 2, 3, 4, 5].sum #=> 15 print [1.2, -4, 4.5, 3, 10].sum #=> 14.7 print
in this case i = [1 2 3 4 5 6] then x = sum(i*p(i)),i.e,'x' is equal to sum of product of corresponding elements of 'i' and 'p'; how to get 'x', i know that we can compute 'x' by using loops.but is there any better way other than loops.0...
