1. Write an Android phone program such that one instance of EditText, one instances of Button, one instance of TextView, and another instance of EditText are displayed vertically on the AVD. The users of your program will be asked to input a positive integer, denoted n, in the first instance of EditText. When the users click the button instance, the binary representa- tion of n will be displayed in the instance of TextView and a specified trian- gular pattern consisting of $'s will be displayed in the second instance of the EditText. For instance, if n = 6, the binary representation should be 110 and the pattern should be $S$$$
