请注意不要看那个samp input和samp output Problem Description Give you a number on base ten,you should output it on base two.(0 n 1000) Input For each case there is a postive number n on base ten, end of file. Output For each case output a number on base two. Sample Input 1 2 3 Sample Output 1 10 11 Problem Description Give you the width and height of the rectangle,darw it. Input Input contains a number of test cases.For each case ,there are two numbers n and m (0 n,m 75)indicate the width and height of the rectangle.Iuput ends of EOF. Output For each case,you should draw a rectangle with the width and height giving in the input.after each case, you should a blank line. Sample Input 3 2 Sample Output Author xhd Problem Description There are many lamps in a line. All of them are off at first. A series of operations are carried out on these lamps. On the i-th operation, the lamps whose numbers are the multiple of i change the condition ( on to off and off to on ). Input Each test case contains only a number n ( 0 n= 10^5) in a line. Output Output the condition of the n-th lamp after infinity operations ( 0 - off, 1 - on ). Sample Input 1 5 Sample Output 1 0 Hint hint Consider the second test case: The initial condition : 0 0 0 0 0 … After the first operation : 1 1 1 1 1 … After the second operation : 1 0 1 0 1 … After the third operation : 1 0 0 0 1 … After the fourth operation : 1 0 0 1 1 … After the fifth operation : 1 0 0 1 0 … The later operations cannot change the condition of the fifth lamp any more. So the answer is 0. Problem Description Give you two numbers A and B, if A is equal to B, you should print YES, or print NO. Input each test case contains two numbers A and B. Output for each case, if A is equal to B, you should print YES, or print NO. Sample Input 1 2 2 2 3 3 4 3 Sample Output NO YES YES NO Problem Description we define f(A) = 1, f(a) = -1, f(B) = 2, f(b) = -2, ... f(Z) = 26, f(z) = -26;Give you a letter x and a n
