;} There is only one difference between the while loop and the Do While loop: the while loop first judges the condition, and then the loop body is formed;Do While loop is the first to do the loop body once, and then determine whether the condition is set up, if set up, then do the loop body, otherwise jump out.in other words, it may be better to use while the initial condition is ambiguous. This depends on your personal habits. limit input, you must enter a number from 0 to 10, otherwise reenter

Because k=3, so any 3 points can not shatter, namely: Α+β≤b (3,3). And because for 2α, X4 is in pairs appear, so, x1,x2,x3 any two points must not shatter, otherwise, plus X4, there will be three points are shatter. namely: Α≤b
