# 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

**Approach:**

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

Below is the implementation of the above approach:

## C++

`// C++ implementation of the approach ` `#include <bits/stdc++.h> ` `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; ` `} ` |

## 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)

**Output:**

Even = 9998 Odd = 9999
