Question

A company is offering a special discount to its customers based on an algorithm. Two range values are fed to the algorithm and in return t will calculate the discount to offer to the customers. The discount is calculated as the sum of all the prime numbers within the defined range including the range values if the range values are the prime numbers

Write an algorithm to find the special discount given to the customers
