Question 14: Create a function that returns the lowest product of 4 consecutive digits in a number given as a string.
This should only work if the number has 4 digits or more. If not, return "Number is too small".
##Example
lowest_product("123456789")--> 24 (1x2x3x4)
lowest_product("35") --> "Number is too small"
This should only work if the number has 4 digits or more. If not, return "Number is too small".
##Example
lowest_product("123456789")--> 24 (1x2x3x4)
lowest_product("35") --> "Number is too small"
# To find lowest product of 4 consecutive digits in a number
