Hello coders, today we are going to solve **Minimize Digit Sum CodeChef Solution** whose Problem Code is **MNDIGSUM**.

Contents

**Task**

Let ** f (n, B)** be the sum of digits of the integer

*when written in base*

**n***.*

**B**Given ** Q** queries, each consisting of three integers

**,**

*n**and*

**l***. Find the value of*

**r****corresponding to which**

*B*

*f*(*n*,

**B****)**is minimum for all

**. If there are multiple such values, you can print any of them.**

*l*â‰¤*B*â‰¤*r***Input Format**

The first line contains in single integer ** Q**, the number of queries

Each of the next Q lines contain three space separated integers

**,**

*n***and**

*l***respectively.**

*r***Output Format**

- For each query (n l r), print the value of base
**B**which lies within**[**such that*l*,*r*]is minimum.*f*(*n*,*B*)

**Constraints**

**Subtasks**

**Subtask #1 (50 points): **original constraints

This problem is worth a total of 50 points and is meant to be complementary to the problem “MNDIGSM2” (also worth 50 points) which is very similar to this problem, but has slightly different constraints.

**Sample Input 1**

** 3
216 2 7
256 2 4
31 3 5**

**Sample Output 1**

` `**6
2
5**

**Explanation**

**Test case 1:** We have ** f (216, 2) = f (216, 3) = 4, f (216, 4) = 6, f (216, 5) = 8, f (216, 6) = 1** and finally

**. Clearly the minimum is obtained when**

*f*(216, 7) = 12**.**

*B*=6**Test case 2:** Note that ** f (256, 2) = f (256, 4) = 2**, therefore both the answers

**2**and

**4**will be considered correct.

**Test case 3:** ** f (31, 3) = f (31, 5) = 3** and

**, therefore both the answers**

*f*(31, 4) = 7**3**and

**5**will be considered correct.
