Below we will define an n-interesting polygon. Your task is to find the area of a polygon for a given n.

A 1-interesting polygon is just a square with a side of length 1. An n-interesting polygon is obtained by taking the n - 1-interesting polygon and appending 1-interesting polygons to its rim, side by side. You can see the 1-, 2-, 3- and 4-interesting polygons in the picture below.

Example

• For n = 2, the output should be
  shapeArea(n) = 5;
• For n = 3, the output should be
  shapeArea(n) = 13.

Code

int shapeArea(int n) {

}

Given an array of integers, find the pair of adjacent elements that has the largest product and return that product.

일련의 정수를 확인하여, 가장 큰 수와 인접한 요소를 찾아 곱한 값을 구하라

Example

For inputArray = [3, 6, -2, -5, 7, 3], the output should be
adjacentElementsProduct(inputArray) = 21.

7 and 3 produce the largest product.

inputArray: [-1, -2]

Expected Output:2

inputArray: [5, 1, 2, 3, 1, 4]

Expected Output: 6

inputArray: [9, 5, 10, 2, 24, -1, -48]

Expected Output: 50

Code

int adjacentElementsProduct(int[] inputArray) {

}

Given the string, check if it is a palindrome.

해당 문자열을 고려하여 회문인지 확인하라

Example

• For inputString = "aabaa", the output should be
  checkPalindrome(inputString) = true;
• For inputString = "abac", the output should be
  checkPalindrome(inputString) = false;
• For inputString = "a", the output should be
  checkPalindrome(inputString) = true.

Code

boolean checkPalindrome(String inputString) {

}

Given a year, return the century it is in. The first century spans from the year 1 up to and including the year 100, the second - from the year 101 up to and including the year 200, etc.

년도를 넣으면 해당세기를 구하라

Example

• For year = 1905, the output should be
  centuryFromYear(year) = 20;
• For year = 1700, the output should be
  centuryFromYear(year) = 17.

Code

int centuryFromYear(int year) {

}

Write a function that returns the sum of two numbers.

두 숫자의 합을 반환하는 함수를 작성합니다.

Example

For param1 = 1 and param2 = 2, the output should be
add(param1, param2) = 3.

Code

int add(int param1, int param2) {

}
