# The Journey Begins

## add

Write a function that returns the sum of two numbers.

#### Example

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

```csharp
int solution(int param1, int param2) {
    return param1 + param2;
}
```

centuryFromYear

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.

#### Example

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

```csharp
int solution(int year) {
    if(year % 100 == 0)
        return (year / 100);
    else 
        return (year / 100 + 1);
}
```

## checkPalindrome

Given the string, check if it is a palindrome.

> Palindrome - A string that doesn't changed when reversed (it reads the same backward and forward). Examples: "eye", "noon", "decaf faced".

#### 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`.

```csharp
bool solution(string inputString) {
    int length = inputString.Length - 1;
    string reverseString = string.Empty; //string reverseString = "";
    while(length >= 0){
        reverseString += inputString[length];
        length--;
    }
    
    if(inputString == reverseString)
        return true;
    else
        return false;
}
```
