Part I: Algorithm #1: infix to postfix Convert an infix expression to postfix: As long as there are more tokens, get the next token. if the token is an operand, append it to the postfix string. if the token is "(", push it onto the stack. if the token is an operator, (order operators by precedence) if the stack is empty, push the operator onto the stack. if the stack is not empty, pop operators of greater or equal precedence from the stack and append them to postfix string, stop when you encounter ")" or an operator of lower precedence or when the stack is empty. And then, push the new operator onto the stack. when you encounter a ")", pop operators off the stack and append them to the end of the postfix string until you encounter matching "(". when you reach the end of the infix string, append the remaining content of the stack to the postfix string. Algorithm #2: Evaluate postfix expressions (Self-study) Note: You must study this using the video prior to your lab. When an operand is entered, pushes it onto a stack. When an operator is entered, applies it to the top two operands of the stack. pops the operands from the stack. pushes the result of the operation on the stack. Part II: Complete method infixToPostfix in Expression class. Test it using the following infix expressions. A + B * C + D (A + B) * (C + D) A * B + C * D A + B + C + D

3. ranga ramasesh is the operations manager for a firm that is trying to decide which one of four countries it should research for possible outsourcing providers. the first step is to select a country based on cultural risk factors, which are critical to eventual business success with the provider. ranga has reviewed outsourcing provider directories and found that the four countries in the table that follows have an ample number of providers from which they can choose. to aid in the country selection step, he has enlisted the aid of a cultural expert, john wang, who has provided ratings of the various criteria in the table. the resulting ratings are on a 1 to 10 scale, where 1 is a low risk and 10 is a high risk. john has also determined six criteria weightins: trust, with a weight of 0.3; quality, with 0.2; religious, with 0.1; individualism, with 0.2; time, with 0.1; and uncertainity, with 0.1. using the factor-rating method, which country should ranga select? why?

"gps interaction and cognitive process" respond to the following: imagine that you have been asked to design a gps product that will have voice recognition and bluetooth capability. discuss and conceptualize a user interaction model. predict two (2) problems that may arise in gps products with voice recognition and bluetooth capability. recommend solutions for each of these issues. attention is one of the six cognition processes. when attention is applied to a design, the goal is to make it easier for the end user to quickly locate where he / she should type information on the computer or mobile device screen. compare and contrast how the google search engine and the microsoft bing search engine employ the attention cognition process. provide your opinion as to which search engine better employs the attention cognition process and explain why.
