The flowchart represents a mathematical algorithm that takes two positive integers as the input and returns a positive integer as the output. Processes are indicated in the rectangular symbols in the flowchart. Each process is symbolized by an equation, such as T = T + a. In this particular process, the current values of the variables T and a are added together and the sum then becomes the value of T. For example, if the value of T is 3 and the value of a is 7 before the process T = T + a is completed, then the value of T is 10 and the value of a is 7 after the process is completed.
　　Use the drop-down menus to fill in the blanks in the following statements based on the algorithm represented by the flowchart.
　　If 24 and 35 are entered as the values for a and b, respectively, then the first nonzero value of T is select..24,48,96,192,384 .
　　If 35 and 27 are entered as the values for a and b, respectively, then after the process  is completed for the second time, the value of3,6,12,13,26 b is select..3,6,12,13,26 .
