+Problem 40
+An irrational decimal fraction is created by concatenating the positive integers:
+
+0.123456789101112131415161718192021...
+
+It can be seen that the 12th digit of the fractional part is 1.
+
+If dn represents the nth digit of the fractional part, find the value of the following expression.
+
+d1 × d10 × d100 × d1000 × d10000 × d100000 × d1000000
