    We as humans write math expression in infix notation, e.g. 5 + 2 (the operators are written in-between the operands). In a computer’s language, however, it is preferred to have the operators on the right side of the operands, i.e. 5 2 +. For more complex expressions that include parenthesis and multiple operators, a compiler has to convert the expression into postfix first and then evaluate the resulting postfix. Write a program that takes an “infix” expression as input, uses...

    You are to write a program name expressionTree.java that evaluates an infix expression entered by the user. The expression may contain the following tokens: (1) Integer constants (a series of decimal digits). (2)   One alphabetic character - "x" (representing a value to be supplied later). (3)   Binary operators (+, -, *, / and % (modulo)). (4)   Parentheses          You will parse the input expression creating an expression tree with the tokens, then use the postOrder tree traversal algorithm to extract...

    In C programming Language Write a version of the infix-to-postfix conversion algorithm. Write a program that converts an ordinary infix arithmetic expression (assume a valid expression is entered) with single-digit integers For Example: Infix expression (6 + 2) * 5 - 8 / 4 to a postfix expression is  62+5*84/- The program should read the expression into character array infix and use the stack functions implemented in this chapter to help create the postfix expression in character array postfix. The...

    This problem uses least squares to find the curve \(y=a x+b x^{2}\) that best fits these 4 points in the plane:$$ \left(x_{1}, y_{1}\right)=(-2,2), \quad\left(x_{2}, y_{2}\right)=(-1,1), \quad\left(x_{1}, y_{3}\right)=(1,0), \quad\left(x_{4}, y_{4}\right)=(2,2) . $$a. Write down 4 equations \(a x_{i}+b x_{i}^{2}=y_{i}, i=1,2,3,4\), that would be true if the line actually went through a11 four points.b. Now write those four equations in the form \(\mathbf{A}\left[\begin{array}{l}a \\ b\end{array}\right]=\mathbf{y}\)c. Now find \(\left[\begin{array}{l}\hat{a} \\ \hat{b}\end{array}\right]\) that minimizes \(\left\|A\left[\begin{array}{l}a \\ b\end{array}\right]-\mathbf{y}\right\|^{2}\).
