There are two types of tables X and Y , let assume the X is the shorter one and Y is more longer. thecombination must be occurred between the two types of tables to be aligned and filling up the givendistance. We can use a few number of tables to cover all the required distance as possible. Hence, you arerequired to find the optimum combination to keep the remaining empty distance is as small as possible.[Hint: the first priority is to minimize the empty distance, and the second priority is to minimize the numberof used tables]Examples:Input: X = 3, Y = 5, D = 24The optimum combination is: TX = 3, TY = 3, RD = 0It means: three tables of size X (TX), three tables of size Y (TY), and remaining distance(RD) is 0. 3 * 3 + 3 * 5 = 24So empty distance = 24 - 24 = 0Input: X = 3, Y = 9, D = 29Output: TX =0, TY = 3, RD = 2It means: zero tables of size X (TX), three tables of size Y (TY), and remaining distance (RD) is 2.0 * 3 + 3 * 9 = 27So empty distance = 29 - 27 = 21- Design an algorithm to…
