其实最终实现的算法与【算术表达式】一样的：
if x == 1
语法：CompareExpression(x == 1)
------------------------------------------------------------------------------
if x == 1 && y == 2 && z == 3
语法：and(and(x == 1, y == 2), z == 3)
------------------------------------------------------------------------------
if x == 1 || y == 2 && z == 3
语法：or(x == 1, and(y==2, z==3))
------------------------------------------------------------------------------
if x == 1 && y == 2 || z == 3
语法：or(and(x==1, y==2), z==3)
------------------------------------------------------------------------------
if (x == 1 || y == 2) && z == 3
语法：and(or(x==1, y==2), z==3)
------------------------------------------------------------------------------
if x == 1 || y == 2 || z == 3
语法：or(or(x == 1, y == 2), z == 3)
------------------------------------------------------------------------------
if x == 1 && y == 2 || c == 3 && (d == 4 || e == 5 && f == 6) && g == 7
语法： or(and(x == 1, y == 2), and(and(c == 3, or(d == 4, and(e == 5, f == 6))), g == 7)
------------------------------------------------------------------------------
if (d == 4 || e == 5 && f == 6) && x == 1 && y == 2 || c == 3 && g == 7
语法： or(and(and(or(d==4, and(e == 5, f==6)), x == 1), y == 2), and(c == 3, g == 7))
