## Pot Of Gold

Rainbows tend to be pretty cool to look at. If you're lucky you'll even find a pot of gold at the end of one. Today's problem is to create a program that generates a random RGB hex value (#7A340E) then prints out the next 100 values (#7A340F, #7A3410, etc.) after that. Afterwards it should print out "POT OF GOLD!!" and then exit.

Quick javascript ```javascript var r = ~~(Math.random() * 255), g = ~~(Math.random() * 255), b = ~~(Math.random() * 255); var currentDigit = 0; console.log("#" + r.toString(16) + g.toString(16) + b.toString(16)); for(var i = 0; i < 100; i++) { if(b >= 254) currentDigit++; if(g >= 254) currentDigit++; b = (b+1) % 255; if(currentDigit==1) g = (g+1) % 255; if(currentDigit==2) r = (r+1) % 255;

``````console.log("#" + r.toString(16) + g.toString(16) + b.toString(16));
``````

} console.log("POT OF GOLD"); ```

Whoops not logged in, here's the javascript with proper formatting

``````var r = ~~(Math.random() * 255), g = ~~(Math.random() * 255), b = ~~(Math.random() * 255);
var currentDigit = 0;
console.log("#" + r.toString(16) + g.toString(16) + b.toString(16));
for(var i = 0; i < 100; i++)
{
if(b >= 254)
currentDigit++;
if(g >= 254)
currentDigit++;
b = (b+1) % 255;
if(currentDigit==1)
g = (g+1) % 255;
if(currentDigit==2)
r = (r+1) % 255;

console.log("#" + r.toString(16) + g.toString(16) + b.toString(16));
}
console.log("POT OF GOLD");

Python solution

``````import random

RGB=[0,0,0]
for i in range(3):
RGB[i]= format(random.randint(0,255), '02X')

for i in range(100):
print  "#"+RGB[0]+RGB[1]+RGB[2]
RGB[2]=format(int(RGB[2], 16)+1, '02X')
if int(RGB[2],16)>255:
RGB[2]=format(0, '02X')

print "Pot of gold!"

``````#python 2.7
import random
x = random.randint(0, 16777215)
i = 1
while i <= 10:
print '#'+ hex(x+i)[2:8].upper()
i = i + 1
print "POT OF GOLD!!"
