TASK DEFINITION: In this task you will be given a list, of lists, of integers. For every inner list contained in the input list, you should multiply every even number in that list. The output should be a list of integers with the same length as the number of lists in the input list. If there are no even numbers in an inner list you should output 0 for that list.
PROBLEM: [[-11, -13, 7, 45, 46], [-5, -20], [6, -15, -6, 17, 26], [46, 26, -25, -47], [-18, -12], [30, -22], [4, 32], [-43, -26], [6, 4, -2, -32], [21, -26, -36, 41], [-14, 24, -31], [20, -16, -15, -50], [50, 30, 5, 46], [-25, -15]]

SOLUTION: [46, -20, -936, 1196, 216, -660, 128, -26, 1536, 936, -336, 16000, 69000, 0]

PROBLEM: [[-21, -32, 1], [19, 31, -9, 40, 24], [49, -12, -36], [1, -17, -4, -47, 30], [-29, -38, -36]]

SOLUTION: [-32, 960, 432, -120, 1368]

PROBLEM: [[22, -19], [-15, 13], [48, -13, 22], [18, -8], [-45, 47, 31, 46], [27, 40, 29, 28, -7], [-1, -19, 49, 33, 26], [12, 31, 20], [16, 39, -37, -10, -14], [-30, 28], [48, -42, -31], [-9, -38, 33, 22]]

SOLUTION:
[22, 0, 1056, -144, 46, 1120, 26, 240, 2240, -840, -2016, -836]
