Seeded Random Horizontal Flip

Problem

Randomly flip images horizontally with probability p using a seeded RNG.

Seed the random module, then for each image draw random.random() and flip it (reversing every row) when the draw is less than p. Return the list of resulting images.

Test cases

case 1

in: [[[[1,2],[3,4]],[[5,6],[7,8]],[[9,10],[11,12]],[[13,14],[15,16]]],0.5,1]

expected: [[[2,1],[4,3]],[[5,6],[7,8]],[[9,10],[11,12]],[[14,13],[16,15]]]

case 2

in: [[[[1,2],[3,4]],[[5,6],[7,8]]],1,2]

expected: [[[2,1],[4,3]],[[6,5],[8,7]]]

case 3

in: [[[[1,2],[3,4]],[[5,6],[7,8]]],0,3]

expected: [[[1,2],[3,4]],[[5,6],[7,8]]]
