Given a list of randomly arranged numbers, for example (6,2,9,5,8,7). Find the total number of upturns in such list. If (a list[b]), then the pair (a, b) is called an upturn of

the list. In the given example, (6,2), (6,5), (9,5), (9,8), (9,7), (8,7) are of possible upturns that

meet the conditions and hence there are 6 upturns in such list.

a) Design a brute-force algorithm to return the number of possible upturns, and analyse

the complexity of your solution (5 marks)

b) Design a more efficient algorithm to do the same task with less complexity, and analyse

the complexity of your solution. (15 marks)

[Important instruction to be followed: Create an arbitrary unsorted list of 6 numbers

and use it to provide full explanation of how your proposed algorithm should work

For this assignment you have to write a c program that will take an infix expression as input and display the postfix expression of the input. after converting to the postfix expression, the program should evaluate the expression from the postfix and display the result. what should you submit? write all the code in a single file and upload the .c file. compliance with rules: ucf golden rules apply towards this assignment and submission. assignment rules mentioned in syllabus, are also applied in this submission. the ta and instructor can call any students for explaining any part of the code in order to better assess your authorship and for further clarification if needed. problem: we as humans write math expression in infix notation, e. g. 5 + 2 (the operators are written in-between the operands). in computer's language, however, it is preferred to have the operators on the right side of the operands, ie. 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 stacks to convert it into postfix expression, and finally evaluates it. it must support the following operations: + - / * ^ % ( example infix expression: (7-3)/(2+2) postfix expression: 7 3 2 2 result: rubric: 1) if code does not compile in eustis server: 0. 2) checking the balance of the parenthesis: 2 points 3) incorrect postfix expression per test case: -2 points 4) correct postfix but incorrect evaluation per test case: -i points 5) handling single digit inputs: maximum 11 points 6) handling two-digit inputs: 100 percent (if pass all test cases)
