My solution to solving the four digits problem was quiet tricky. It is hard at first but when their becomes less numbers it starts to pour out of you. I started with the largest odd number to try seeing if it was the biggest I could get it before I started the other numbers. When I finally decided on what number I was going to do I came out with 9763. It is not that big but I had to save all the other numbers so it wasn’t the only one to shine.
Then I began with the closest to 5000. At first I started with 4998 but soon realized that all the numbers consisting of 4998 were way too big and had to be saved for bigger numbers. So I decided that I wasn’t probably going to use the two 00, so I decided to with a satisfying 5001.
Then with the multiple of three I started with 8649, soon realizing that it wasn’t the biggest number I could make. After jiggling around with some numbers (which you should always do) I ended up with 9846.
When looking for the next number to stat with I soon came across that I hadn’t done the largest even number. Looking at my numbers I had 84721235. I used the largest numbers then used the rest for the smallest multiple of 5. When eventually finalizing all the numbers I ended up with 8763. Leaving 1235.
