01. You are given a function, int Distance(int Ax, int Ay, int Bx, int By); The function accepts the coordinates of truck A(Ax, Ay) and the coordinates of truck B(Bx, By), as input. The office is at location (0, 0). Implement the function to determine which truck is closer to the office by comparing the square of their distances. Return the square of the distance of the truck which is closer to the office. Square of distance between two points having coordinates (x, y) and (0, 0): (Distance) [x²+ y²] = 82645-3997956 02. 03. Note: D •No need to compute the square root of the distances of trucks A and B from the office. • If both trucks are at equal distance, return square of distance of either truck. Example: Input: 12 5 12 9 Output: 169 Explanation: (Distance of truck A)² = (Ax² + Ay²] = [12²+52) = (144 +25) = 169 (Distance of truck B)2= [Bx²+ By2] = [122+92] = (144 +81) = 225 Since, (169225), hence the output is 169. Sample input 6 8 3 4 sample output 25
