Public static int aboveBenchmarck(int benchmark, int[] arr) this method returns the number of values in the arr that are equals to or greater than the benchmark value. Once completed, please test your methods as follows: 1. Define a 30 elements int array
2. Assign random numbers in the range of [50, 100], to each element of the int arr
3. Call each method and print the values returned by each method call. For the aboveBenchmarck method, use 80 as benchmark value.

Jessie has received a contract to build a real-time application for a baker. however, the baker doesn't want to invest too much money. his only requirement is that he wants the customers to know which cupcakes are available at what time and in what quantity. so his core requirement is that the details of product should be in real time. what platform can jessie use to develop this application?

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 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: 1guidelines: 1. you will need to use stacks in three placesa. one for the parenthesis check [char stack]b. one during infix to postfix [char stack]c. one during evaluation [int stack]for a and b above, you can use same array and same push, pop method as both ofthem are char. but for evaluation you have int stack and you might consider to createanother push pop method to handle it. maybe push_int, pop_int, etc. or find otherstrategy to utilize existing push pop method2. you can create a function for obtaining operator priority. that function should take anoperator as input and return its priority as an integer. this function will you a lot andreduce repeated code3. during evaluation you will need to convert char into integer. example for single digit: char c = '5'; int x = c - '0';
