TriathlonCompetitor Scheduling You are trying to schedule triathlon contestants so that the triathlon completes as early in the day as possible. (The triathlon completes when all the contestants are done.) Each contestant has a projected swimming time, running time, and biking time. Since the pool is very small only one contestant can be in the pool at a time. Any number of contestants can be biking and running at the same time. The contestants first swim, then bike, and finally run. Assuming that each contestant will complete each event in their projected time, what is the best order to send the people out, if you want the whole competition to be over as soon as possible? That is, give and efficient algorithm that produces a schedule whose completion time is as early as possible. A. Specify an efficient greedy algorithm to achieve the goal of earliest completion of the competition.
B. Prove your algorithm always finds the optimal solution.
C. Analyze your algorithm's complexity.

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';
