There are two kinds of people, the ones who like numbers and the ones who hate numbers. This challenge is for those who like numbers. This one will keep you busy for some time. Try to find the 10 digit number X0X1X2X3X4X5X6X7X8X9 so that the each X shows the times its number appears in the 10 digit number. X0 shows how many times 0 appears in the number, X3 shows how many times 3 appears in the number and so on. The difficulty of this is about 60/100 so let me know if you like it and if you want more difficult problems. After you find it, post it in a comment.
