Directional Quality Control
A quality control system checks items in two directions: North-South and East-West. The score of each item is calculated as the product of the two directional scores. Given the score arrays for both directions, calculate the total quality score as the sum of all possible products of pairs (one from each array). The input will be two lines, each containing integers separated by spaces. Print the total quality score.
Example input:
2 3 4
1 5 6
Example output:
56
