input and output the correct value in ohms. +The color bands are encoded as follows: + +| Color | Value | +| ------ | ----- | +| Black | 0 | +| Brown | 1 | +| Red | 2 | +| Orange | 3 | +| Yellow | 4 | +| Green | 5 | +| Blue | 6 | +| Violet | 7 | +| Gray | 8 | +| White | 9 | + +In [`Resistor Color Trio`][resistor-color-trio-exercise] you decoded the first three color bands. +For instance: orange-orange-brown translated to the main value `330`. +In this exercise you will need to add _tolerance_ to the mix. +Tolerance is the maximum amount that a value can be above or below the main value. +For example, if the last band is green, the maximum tolerance will be `±0.5%`. + +The tolerance band will have one of these values: + +| Color | Tolerance | +| ------ | --------: | +| Grey | ±0.05% | +| Violet | ±0.10% | +| Blue | ±0.25% | +| Green | ±0.50% | +| Brown | ±1.00% | +| Red | ±2.00% | +| Gold | ±5.00% | +| Silver | ±10.00% | + +The four-band resistor is built up like this: + +| Band_1 | Band_2 | Band_3 | Band_4 | +| ------- | ------- | ---------- | --------- | +| Value_1 | Value_2 | Multiplier | Tolerance | + +Examples: + +- orange-orange-brown-green would be `330` ohms with a `±0.5%` tolerance. +- orange-orange-red-grey would be `3300` ohms with a `±0.05%` tolerance. + +The difference between a four and five-band resistor is that the five-band resistor has an extra

+There are also one band resistors. +One band resistors only have the color black with a value of 0. + +Your program should translate an input `list` of resistor band colors into a label: + +"... ohms ±...%" + +So an input `list` of `["orange", "orange", "black", "green"]` should return: + +"33 ohms ±0.5%" + +When there are thousands of ohms, we say "kiloohms". +That's similar to saying "kilometer"
