Given the integer variables x , y , and z , write a fragment of code that assigns the smallest of x , y , and z to another integer variable min . Assume that all the variables have already been declared and that x , y , and z have been assigned values,So if the value of x is 19 the value of y is 13, and the value of z is 23, then after your code executes, the value of min would be 13.
