Describe
a positive integer, if it is divisible by 7, or the number in a certain place in its decimal representation is 7, then it is called a number related to 7. Now find all the numbers less than or equal to n (n <100) The sum of squares of positive integers not related to 7.
Input The
input is one line, and the positive integer n (n <100) is
output. The
output line contains an integer, that is, the sum of the squares of all positive integers that are less than or equal to n and not related to 7.
Sample input
