The problems focuses on testing your programmatic, algorithmic and code writing skills. We would love to get the solutions the "Object Oriented" way. Do not copy :)

Problem 1: write a function to get the value from an array in such a way that the keys are sparated by a dot.

function array_take($array, $keymap) {
    # your code goes here...
}
$person = [
    'name' => [
        'firstname' => 'Raj',
        'lastname' => 'Ankur'
    ],
    'employee' => [
        'engineering' => [
            'position' => 'Hacking Intern'
         ]
     ]
];

In the below statement $x should be equal to 'Hacking Intern':

$x = array_take($person, 'employee.engineering.position');

Problem 2: Assume you have a web page opened: "https://www.picsdream.com/search?q=a&cities=delhi&area=chanakya-puri". Write a function input() that does following operations.

echo input(); # Output 1: q=a&cities=delhi&area=chanakya-puri
echo input('q'); # Output 2: a
echo input(['q', 'cities']); # Output 3: q=a&cities=delhi
count(input(['q', 'cities'])); # Output 4: 2
count(input()); # Output 5: 3
echo input()->append(['another_var' => 'value']); # Output 6: q=a&cities=delhi&area=chanakya-puri&another_val=value
echo input()->append(['another_var' => 'value'])->except('a'); # Output 7: cities=delhi&area=chanakya-puri&another_val=value

Problem 3: Write a function to return current financial year

function fy() {
    #Your code goes here
}
echo fy(); // Output: 2018-19

Problem 4: Write a function to beautify numbers in such a way that the number is Round-up of Round-down to nearest 49 or 99

function beautify_price() {
    #Your code goes here
}
echo beautify_price(26); // Output: 49
echo beautify_price(78); // Output: 99
echo beautify_price(69); // Output: 49
echo beautify_price(1715); // Output: 1699
echo beautify_price(2489); // Output: 2499

Problem 5: What will be the output of following JavaScript code snippet? Explain your answer.

const numbers = [1, 2, 3, 4];
for (var i = 0; i < numbers.length; i++) {
  setTimeout(function() {
    console.log('index: ' + i + ', element: ' + numbers[i]);
  }, 5000);
}
