Dev Skill team likes to test intelligence of internship candidates through various puzzle questions. One of such question was to ask the distance between two opposite corners of a box. A box is considered to be a 3D object and all its sides have 90 degree angle with the opposite plane – that is all sides creates 90 degree corner with its adjacent sides. ![box image][1] Please check the box above. All its corners are marked with letters ‘A’ to ‘H’ and a red line is drawn between ‘A’ and ‘D’. In this problem you need to measure the length of AD. We will provide you 3 lengths AB, BC and CD. You need to measure AD as output. Input: ------ Input starts with an integer **T (≤ 30)**, denoting the number of test cases in first line of input. Each test case will have 3 numbers separated by space in a line of its own, which denotes AB, BC and CD in sequence. All these 3 numbers are greater than zero and less than 1000. Number can be fractional as well but none of them will have more than 2 digits after the decimal place. Output: ------- For each test case, print the length of AD in a line with up to 2 decimal places. Sample Input ------------ 3 1 1 1 1.0 1.0 1.0 3.00 3.00 3.00 Sample Output ------------- 1.73 1.73 5.20 [1]: https://s3-ap-southeast-1.amazonaws.com/devskillimagestorage/questionimages/dacbe9f2-6b16-c1f1-1cb5-08d2e21f106b_cb4b92e720da4a30ae719bff896f94ef_W313xH222.png
