Question 1 How to Attempt? Charles and the Necklace Charles wants to buy a necklace in which 1. There is a minimum of 1 pearl and maximum of X pearls, such that each pearl has its own magnificent coefficient. 2. The pearls should be in non-decreasing order of their magnificence power. Revisit Later You are given the maximum number of pearls in a necklace and the range of the magnificent coefficients of the pearls. Find the number of necklaces that can be made that follow the mentioned conditions. Input Specification: input1: Maximum number of pearls that can be used to form the necklace input2: Starting magnificent coefficient of pearls input3: Ending magnificent coefficient of pearls Output Specification: Return the number of necklace options possible as per given conditions Example 1: input1: 1 input2: 4 tests ment input2: 4 input3: 5 Output: 2 Explanation: Necklace can be formed using one pearl of either magnificence coefficient 4 or magnificence coefficient 5. hence total number of perfect necklaces are 2. Example 2: input1: 2 input2: 8 input3: 9 h Output: 5 Explanation: Necklace can be formed using two pearls of either magnificence coefficients (8,8) or (8.9) or (9.9), or using one pearl of either magnificence coefficient 8 or 9, hence total number of perfect necklaces are 5.
