# Find the Batting Average of a batsman

Given three integers **runs**, **matches**, and **not-out** representing the number of runs scored, number of innings played by the batsman and number of times he remained Not Out respectively, the task is to calculate the Batting Average of the batsman.

where

**Note:** If the batsman was never dismissed, print “NA” as the no average can be defined.

**Examples:**

Input:runs = 10000, matches = 250, not-out = 50Output:50Explanation:

Number of times batsman was dismissed = 250 – 50 = 200

Batting Average = 10000 / 200 = 50.

Input:runs = 100, matches = 1, not-out = 1Output:NA

**Approach:**

Follow the steps below to solve the problem:

- Calculate the number of dismissals, equal to
**matches – notout**. - Calculate the Batting Average, equal to
**runs/ (matches – notout)**.

Below is the implementation of the above approach:
