Descriptions of Shapes a) A quadrilateral with a vertical line of symmetry but no horizontal line of symmetry: Imagine an isosceles trapezoid where the top and bottom bases are parallel, and the non-parallel sides are of the same length. This shape would have a vertical line of symmetry (cutting it vertically through the middle) but …
Example 29: (a AND b) OR (NOT c AND d) Read ‘(‘ and push onto stack: Stack = ( Read ‘a’ and add to output: Output = a Read ‘AND’ and push onto stack: Stack = (, AND Read ‘b’ and add to output: Output = ab Read ‘)’ and pop operators until ‘(‘: Output …
Example 26: ((a + b) ^ c – d * e / f) + g * h Read ‘(‘ and push onto stack: Stack = ( Repeat steps for inside expression (a + b): Output = ab+ Read ‘^’ and push onto stack: Stack = (, ^ Read ‘c’ and add to output: Output = …
Example 22: (a + b) * (c / d – e ^ f) / g Read ‘(‘ and push onto stack: Stack = ( Read ‘a’ and add to output: Output = a Read ‘+’ and push onto stack: Stack = (, + Read ‘b’ and add to output: Output = ab Read ‘)’ and …
Example 14: (x + y) * z / a – b Read ‘(‘ and push onto stack: Stack = ( Read ‘x’ and add to output: Output = x Read ‘+’ and push onto stack: Stack = (, + Read ‘y’ and add to output: Output = xy Read ‘)’ and pop operators until ‘(‘: …
Example 14: (x + y) * z / a – b Read ‘(‘ and push onto stack: Stack = ( Read ‘x’ and add to output: Output = x Read ‘+’ and push onto stack: Stack = (, + Read ‘y’ and add to output: Output = xy Read ‘)’ and pop operators until ‘(‘: …
Example 10: (a – b) * c – d Read ‘(‘ and push onto stack: Stack = ( Read ‘a’ and add to output: Output = a Read ‘-‘ and push onto stack: Stack = (, – Read ‘b’ and add to output: Output = ab Read ‘)’ and pop operators until ‘(‘: Output = …
Example 6: (a – b) / (c * d) Read ‘(‘ and push onto stack: Stack = ( Read ‘a’ and add to output: Output = a Read ‘-‘ and push onto stack: Stack = (, – Read ‘b’ and add to output: Output = ab Read ‘)’ and pop operators until ‘(‘: Output = …
Infix to Postfix Conversion Infix to Postfix Conversion Example 1: a + b Read ‘a’ and add to output: Output = a Read ‘+’ and push onto stack: Stack = + Read ‘b’ and add to output: Output = ab Finish by popping operators from stack to output: Output = ab+ Final Result: ab+ Example …
