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: [[26, 3], [-44, 15, 6, 31, -28], [32, -26, 27], [-18, 7, -22], [29, 38, -47], [-13, 44], [-36, -45], [-28, 45, -6, -24], [0, 34, 37, -12], [-14, 15], [-30, 21, 23, 2, 43], [36, -25, -14, 35]]

SOLUTION: [26, 7392, -832, 396, 38, 44, -36, -4032, 0, -14, -60, -504]

PROBLEM: [[-8, 23, 0, 29], [-9, 19, -40, 19], [31, -35, 17], [18, 30, 38], [7, -48, -19], [-14, 39], [-21, -2, -15, 7]]

SOLUTION: [0, -40, 0, 20520, -48, -14, -2]

PROBLEM: [[-29, -29, -22], [-11, 45, -50, -16, 15], [-35, 48, 8, -18, 22], [-5, -49, 26, 19, -8], [-11, -14, 44, 28, 37]]

SOLUTION:
