Test Status Code Input and Output
1   Pass
x = '5/(s+2)'; y_correct = 2.5; assert(isequal(DC_gain(x),y_correct))

x = '5/(0+2)' ans = 2.5000

2   Pass
x = '5/(s+5)'; y_correct = 1; assert(isequal(DC_gain(x),y_correct))

x = '5/(0+5)' ans = 1

3   Pass
x = '5/(2*s+5)'; y_correct = 1; assert(isequal(DC_gain(x),y_correct))

x = '5/(2*0+5)' ans = 1

4   Pass
x = '10/(2*s+5)'; y_correct = 2; assert(isequal(DC_gain(x),y_correct))

x = '10/(2*0+5)' ans = 2
