Given three positive integers **x**, **y** and **n**, the task is to find count of all numbers from 1 to n that can be formed using x and y. A number can be formed using x and y if we can get it by adding any number of occurrences of x and/or y.

**Example 1:**

Input:x =2,y =3,n =10Output:9Explanation:We can form 9 out of 10 numbers using 2 and 3 and 10; 2 = 2, 3 = 3, 4 = 2+2, 5 = 2+3, 6 = 3+3 7 = 2+2+3, 8 = 3+3+2, 9 = 3+3+3 , 10 = 3+3+2+2.

**Example 2:**

Input:x =5,y =7,n =10Output:3Explanation:We can form 3 out of 10 numbers using 5 and 7 and 10; 5 = 5, 7 = 7, 5+5 = 10.

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **getCount()** which takes 3 Integers x,y and n respctively as input and returns the answer.

**Expected Time Complexity:** O(n)

**Expected Auxiliary Space:** O(n)

**Constraints:**

1 <= x,y,n <= 10^{5}
