Question

A group of friends have decided to participate in a game called "The Hunting Games". The first stage of the game is to gather some supplies. They have a list and your job is to help them follow it and make the needed calculations.

Write a program that calculates the needed provisions for a quest in the woods.

First you will receive:

• the days of the adventure,
• the count of the players
• group’s energy.

Afterwards, you will receive the following provisions per day for one person:

• Water
• Food

The group calculates how many supplies they’d need for the adventure and take that much water and food.

Every day they chop wood and lose a certain amount of energy. For each of the days, you are going to receive the energy loss from chopping wood. The program should end If the energy reaches 0 or less.

Every second day they drink water, which boosts their energy with 5% of their current energy and at the same time drops their water supplies by 30% of their current water.

Every third day they eat, which reduces their food supplies by the following amount:

• {currentFood} / {countOfPeople} and at the same time raises their group’s energy by 10%.

The chopping of wood, the drinking of water, and the eating happen in the order above.

If they have enough energy to finish the quest, print the following message:

"You are ready for the quest. You will be left with - {energyLevel} energy!"

If they run out of energy print the following message and the food and water they were left with before they ran out of energy:

"You will run out of energy. You will be left with {food} food and {water} water."

Input / Constraints:

• On the 1st line, you are going to receive a number N - the days of the adventure – an integer in the range [1…100]
• On the 2nd line – the count of players – an integer in the range [0 – 1000]
• On the 3rd line - the group’s energy – a real number in the range [1 - 50000]
• On the 4th line – water per day for one person – a real number [0.00 – 1000.00]
• On the 5th line – food per day for one person – a real number [0.00 – 1000.00]
• On the next N lines – one for each of the days – the amount of energy loss– a real number in the range [0.00 - 1000]
• You will always have enough food and water.

Output:

• "You are ready for the quest. You will be left with - {energyLevel} energy!" – if they have enough energy
• "You will run out of energy. You will be left with {food} food and {water} water." - if they don't.

All of the real numbers should be formatted to the second digit after the decimal separator

Answer 1

Here is my solution:

<?php

$days = intval(readline());
$players = intval(readline());
$groupEnergy = floatval(readline());
$waterPerDayPerPerson = floatval(readline());
$foodPerDayPerPerson = floatval(readline());

$water = $waterPerDayPerPerson * $players * $days;
$food = $foodPerDayPerPerson * $players * $days;

for ($i = 1; $i <= $days; $i++) {
    $energyLoss = readline();
    $groupEnergy -= $energyLoss;

    if ($groupEnergy <= 0) {
        break;
    }

    if ($i % 2 == 0) {
        $groupEnergy += $groupEnergy * 0.05;
        $water -= $water * 0.3;
    }

    if ($i % 3 == 0) {
        $food = $food - ($food / $players);
        $groupEnergy += $groupEnergy * 0.1;
    }
}

if ($groupEnergy > 0) {
    printf("You are ready for the quest. You will be left with - %.2f energy!", $groupEnergy);

} else {
    printf("You will run out of energy. You will be left with %.2f food and %.2f water.", $food, $water);
}
