Background: As noted in the previous exercises, we can represent colors as RGB values. That is$,$ as $3$ integers representing the amount of red, green, and blue in the color. In this exercise, we will represent RGB values as $9$ digit integers, where the leftmost three digits represent red, the next three digits represent green, and the last three digits represent blue. Each of the red, green, and blue values are between $0$ and $255($inclusive$),$ where $255$ is "entirely on$"$ and $0$ is "entirely off".

For example, the RGB values of orchid $($a purplish color$)$ are $218,112,$ and $214.$ We will represent that as the single integer $218112214.$

Note that the integer does not necessarily have to be nine digits, since it could contain leading zeroes. For example, if the RGB values are $000,032,175,$ then we will represent that as the single integer $32175.$

With this in mind, write the function blendColors$($rgb$1,$ rgb$2),$ which takes two rgb values, and returns a new rgb value where the red, green, and blue are each halfway between the corresponding part of the two original colors. For Example, blendColors$(204153050,104000152)$ should return the value $154077101$ because $154$ is halfway between $204$ and $104,77$ is halfway between $153$ and $0,$ and $101$ is halfway between $50$ and $152.$

Hint: Each of the red, green, and blue parts must be rounded to the nearest integer $(0\mathrm{.}5$ should be rounded up$),$ not kept as floats.
