Consider the following program: fucntion foo(a,b,c) { let x = y = 0; if (a > 0) { y = 7;} else {y = 5;} if (b > 3) { x = 2;} assert (x+y!=5); } a. Please execute the program symbolically and show the path constraints based on symbolic values. (hint: show the value changes and branch decisions.) b. Please manually solve the path constraints and identify one representative input for each path, if possible..
