Image Decode Size Estimate

Problem

Estimate the decoded pixel height of an encoded image.

Given the encoded size in bytes, the decoded width and the bits per pixel, return round(file_bytes * 8 / (width * bits_per_pixel)) as an integer.

case 1

in: [1200,100,8]

expected: 12

case 2

in: [900,30,8]

expected: 30

case 3

in: [100,10,8]

expected: 10

case 4

in: [2400,200,16]

expected: 6
