Range is the difference between the highest & the lowest values of the set, which can be equal to the standard deviation only if all numbers in the set are equal
Also we know that the standard deviation of any set of numbers is always greater than or equal to zero, where zero is the standard deviation in only those sets in which all values are equal and in rest of the cases the standard deviation is strictly positive.
So, the standard deviation as well as the range of the set of equal numbers must be zero. Hence the answer is 0.
