Error

Given a number N, change all bits at even positions to 0.

**Example 1:**

**Input**: N = 30
**Output:** 10
**Explanation**: Binary representation of
**1**1**1**1**0**. Bits at Even positions are
highlighted. After making all of them
0, we get **0**1**0**1**0. **Hence the answer is 10.

**Example 2:**

**Input: **N = 10
**Output: **10
**Explanation**: Binary representation of
1**0**1**0**. Bits at Even positions are
highlighted. After making all of them
0, we get 1**0**1**0.** Hence the answer is 10.

**Your Task: **

You dont need to read input or print anything. Complete the function **convertEvenBitToZero() **which takes n as input parameter and returns the value of N after changing bits at even positions.

**Expected Time Complexity:** O(1)

**Expected Auxiliary Space:** O(1)

**Constraints:**

1<= N <=(32-bit number)
