NettetIn one move you can swap two adjacent values. You want to perform a minimum number of moves, such that in the end there will exist a subsegment 1, 2, …, k, in other words in the end there should be an integer i, 1 ≤ i ≤ n − k + 1 … NettetThere's a chip in the point (0, 0) (0,0) of the coordinate plane. In one operation, you can move the chip from some point (x_1, y_1) (x1,y1) to some point (x_2, y_2) (x2,y2) if the Euclidean distance between these two points is an integer (i.e. \sqrt { (x_1-x_2)^2+ (y_1-y_2)^2} (x1 − x2)2 +(y1 −y2)2 is integer).

NettetYou are given two positive integers aa and bb. In one move you can increase aa by 11 (replace aa with a+1a+1). Your task is to find the minimum number of moves you need to do in order to make aa divisible by bb. It is possible, that you have to make 00 moves, as aa is already divisible by bb. You have to answer tt independent test cases. Input NettetJohn and his imaginary friend play a game. There are n lamps arranged in a circle. Lamps are numbered 1 through n in clockwise order, that is, lamps i and i + 1 are adjacent for … NettetInput.
