# Largest Even and Odd N-digit numbers

Given an integer N, the task is to find the largest even and odd N-digit numbers.

Examples:

Input: N = 4
Output:
Even = 9998
Odd = 9999

Input: N = 2
Output:
Even = 98
Odd = 99

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach:

• Largest N-digit even number will be (10n) – 2 because the series for different values of N will be 8, 98, 998, 9998, …..
• Similarly, largest N-digit odd number will be (10n) – 1 for the series 9, 99, 999, 9999, …..

Below is the implementation of the above approach:

## C++

 `// C++ implementation of the approach ` `#include ` `using` `namespace` `std; ` ` `  `// Function to print the largest n-digit ` `// even and odd numbers ` `void` `findNumbers(``int` `n) ` `{ ` `    ``int` `odd = ``pow``(10, n) - 1; ` `    ``int` `even = odd - 1; ` `    ``cout << ``"Even = "` `<< even << endl; ` `    ``cout << ``"Odd = "` `<< odd; ` `} ` ` `  `// Driver code ` `int` `main() ` `{ ` `    ``int` `n = 4; ` `    ``findNumbers(n); ` ` `  `    ``return` `0; ` `} `

## Java

 `// Java implementation of the approach ` `class` `GFG { ` ` `  `    ``// Function to print the largest n-digit ` `    ``// even and odd numbers ` `    ``static` `void` `findNumbers(``int` `n) ` `    ``{ ` `        ``int` `odd = (``int``)Math.pow(``10``, n) - ``1``; ` `        ``int` `even = odd - ``1``; ` `        ``System.out.println(``"Even = "` `+ even); ` `        ``System.out.print(``"Odd = "` `+ odd); ` `    ``} ` ` `  `    ``// Driver code ` `    ``public` `static` `void` `main(String args[]) ` `    ``{ ` `        ``int` `n = ``4``; ` `        ``findNumbers(n); ` `    ``} ` `} `

## C#

 `// C# implementation of the approach ` `using` `System; ` `class` `GFG { ` ` `  `    ``// Function to print the largest n-digit ` `    ``// even and odd numbers ` `    ``static` `void` `findNumbers(``int` `n) ` `    ``{ ` `        ``int` `odd = (``int``)Math.Pow(10, n) - 1; ` `        ``int` `even = odd - 1; ` `        ``Console.WriteLine(``"Even = "` `+ even); ` `        ``Console.Write(``"Odd = "` `+ odd); ` `    ``} ` ` `  `    ``// Driver code ` `    ``public` `static` `void` `Main() ` `    ``{ ` `        ``int` `n = 4; ` `        ``findNumbers(n); ` `    ``} ` `} `

## Python3

 `# Python3 implementation of the approach ` ` `  `# Function to print the largest n-digit ` `# even and odd numbers ` `def` `findNumbers(n): ` ` `  `    ``odd ``=` `pow``(``10``, n) ``-` `1` `    ``even ``=` `odd ``-` `1` `    ``print``(``"Even = "``, even) ` `    ``print``(``"Odd = "``, odd) ` ` `  `# Driver code ` `n ``=` `4` `findNumbers(n) ` ` `  `# This code is contributed by ihritik `

## PHP

 ` `

Output:

```Even = 9998
Odd = 9999
```
