Square Root with Decimal Precision Problem Statement

You are provided with two integers, 'N' and 'D'. Your objective is to determine the square root of the number 'N' with a precision up to 'D' decimal places. This implies that the discrepancy between your computed result and the correct value should be less than 10^(-D).

Example:

Input:

N = 10, D = 3

Output:

3.162

Explanation:

If N = 10 and D = 3, the resulting square root is 3.162.

Input:

The first line of the input consists of a single positive integer 'T', representing the number of test cases. Each test case will have a line with two space-separated positive integers 'N' and 'D', which correspond to the number for which you are finding the square root and the precision in decimal places required.

Output:

For each test case, output a single line with a number representing the square root of 'N' such that the precision of the result - i.e. the difference versus the true square root - is less than or equal to 10^(-D). Each test case will be output on a new line.

Constraints:

• 1 <= T <= 10^4
• 1 <= N <= 10^15
• 1 <= D <= 6
• Time limit: 1 sec.

Note:

There is no need for manual output; simply implement the function as described, and the system will handle printing.
