numbers 84, I .e. 01010100 (2) from the left, the numbers 3, 4, 5, 7, and 8 are as follows:01010100 (2) 00111011 (2)00010000 (2)That is, a = 84, B = 59C = A B = 16C language source code:# Include Main (){Int A = 84;Int B = 59;Printf ("% d", A B );}
2. "bitwise OR" Operator (|)If one of the two binary bits is 1, The result value of this bits is 1. In logic or operations, it is true.
.For example, 60 (8) | 17 (8), bitwise OR operation is performed on October 60 and October 17.00110000| 00001111

first instruction that gives the coordinates of the starting position. You may assume there is no more than instructions in each test case, and all the integer coordinates is in the range (-300, 300). The input is terminated if N is 0.OutputFor each test case there'll be one output line in the formatCase X:there is w pieces.,where x is the serial number starting from 1.Note:the figures below illustrate the and the sample input cases.
