Print age (with.Java)

This is an article looking into the “age output” problem.

As I solve coding test problems, I look back on the problems I solved and look into different solution methods to learn more.

Let’s look at the problem first.

problem

I wondered what year the shy 40-year-old teacher was born.

When age is given, please complete the solution function that returns the year of birth based on 2022.

Restrictions

0 < age ≤ 120

Age is 1 year in the year of birth and increases by 1 for each year.

Input/Output Example

My solution to the problem

class Solution {
     public int solution(int age) {
         int answer = 0;
         answer = 2022 - age + 1;
         return answer;
     }
}

Solution explanation

Based on 2022, we wrote the code answer = 2022 - age + 1;: to reflect the fact that the age is subtracted from the value starting from 1 year old to satisfy the restrictions.
