**Minimum Deletions to Make Array Beautiful** – You are given a **0-indexed** integer array `nums`

. The array `nums`

is **beautiful** if:

`nums.length`

is even.`nums[i] != nums[i + 1]`

for all`i % 2 == 0`

.

# Minimum Deletions to Make Array Beautiful

Note that an empty array is considered beautiful.

You can delete any number of elements from `nums`

. Minimum Deletions to Make Array Beautiful, When you delete an element, all the elements to the right of the deleted element will be **shifted one unit to the left** to fill the gap created and all the elements to the left of the deleted element will remain **unchanged**.

Return *the minimum number of elements to delete from *

`nums`

*to make it*

*beautiful.*

**Minimum Deletions to Make Array Beautiful Example 1:**

Input:nums = [1,1,2,3,5]Output:1Explanation:You can delete either`nums[0]`

or`nums[1]`

to make`nums`

= [1,2,3,5] which is beautiful. It can be proven you need at least 1 deletion to make`nums`

beautiful.

**Minimum Deletions to Make Array Beautiful Example 2:**

Input:nums = [1,1,2,2,3,3]Output:2Explanation:You can delete`nums[0]`

and`nums[5]`

to make nums = [1,2,2,3] which is beautiful. It can be proven you need at least 2 deletions to make nums beautiful.

**Constraints:**

`1 <= nums.length <= 10`

^{5}`0 <= nums[i] <= 10`
