# Python
# Secret Sharing procedure
# Secret code is split into 3 partial secret codes
# Codes have 3 digits
# Three three-digit codes (x,y,z) are put into the function calculating the secret code
# The three codes (I, J, K) are the coordinates of an isosceles triangle
# The base of the isosceles triangle is IJ
# The height of the isosceles triangle is h
# The first three decimal places of the height are the secret code
