A code a, a, a3 a, uses the last last digit, a4, as the check digit. The check digit is found using the formula 6 a, + 3 a, + 2 a, mod 9 Will this check digit find all transposition errors in the first and second positions? Yes, it will find all transposition errors ONo, it will miss errors where |a, - a,| = 1 ONo, it will miss errors where |a, - a2l DNo, it will miss errors where |a, - a,| = 3 ONo, it will miss errors where |a, - a2| = 4 ONo, it will miss errors where |a, - a,| ONo, it will miss errors where |a, - a2l ONo, it will miss errors where |a, - a2l = 7 ONo, it will miss errors where |a, - a,| = 8 ONo, it will miss errors where |a, - a,| = 9 = 2 = 5 %3D Ln O

Write a cpp code for x, y, z coordinate as the two colliding spheres are 3D spheres and it also asks if the distance between their two centers is less than or equalto the sum of their radii. The distance D between 2 spheres with centers (x1, y1, z1) and (x2, y2, z2) is given by the formula: D = V[(x2 - x1)² + (y2 - y1)? +(z2 - z1)²] %3D
