DCP-31: Divide and Fool Back to All Problems

Easy Beginners Problems > Ad-hoc


Arif is just a 1st year computer science student. His elder brother Hasan on the other hand is a 4th year computer science student and a very good programmer. But Hasan is a bit naughty and he likes to make fun of his younger brother by giving him task to fool him. This time Hasan told his brother Arif to write a program that takes 2 integers as input and prints the division result but the only condition is he has to print up to a certain digit with accuracy. Arif being a new programmer feels this is an easy task and writes the code. But unfortunately his program does not print the result accurately enough after the decimal point and fails for the following input: **X = 22, Y = 7, P = 25** Here X is the 1st number, Y is the 2nd number and P is the total digits after the decimal place that he needs to print for the division result. Arif’s program prints the result as: **3.14285714285714** but the correct result should be: **3.1428571428571428571428571**. Arif feels sad as he has failed the challenge again, but this time he asks for your help to complete the task. Please help poor Arif in this problem. Input: ------ First line of the input will consist of an integer which represent the test case **T (0<T<=30)**. Each test case contains 3 integers X, Y, P. You can assume **(0 > X, Y, P <=100)**, that is X, Y and P all will be greater than zero and less than or equal to 100. Your task is to divide X with Y until you print P digits after the decimal point of the result. Output: ------- For each test case print the division result as mentioned above in its own line. Sample Input ------------ 3 22 7 25 4 2 10 1 12 7 Sample Output ------------- 3.1428571428571428571428571 2.0000000000 0.0833333
