:PROPERTIES:
:NEETCODE: [[file:../../roadmap.org::*0746. Min Cost Climbing Stairs][0746. Min Cost Climbing Stairs]]
:END:

You are given an integer array ~cost~ where ~cost[i]~ is the cost of ~i^{th}~ step on a staircase. Once you pay the cost, you can either climb one or two steps.

You can either start from the step with index ~0~, or the step with index ~1~.

Return /the minimum cost to reach the top of the floor/.

*Example 1:*


#+begin_src
Input: cost = [10,15,20]
Output: 15
Explanation: You will start at index 1.
- Pay 15 and climb two steps to reach the top.
The total cost is 15.
#+end_src


*Example 2:*


#+begin_src
Input: cost = [1,100,1,1,1,100,1,1,100,1]
Output: 6
Explanation: You will start at index 0.
- Pay 1 and climb two steps to reach index 2.
- Pay 1 and climb two steps to reach index 4.
- Pay 1 and climb two steps to reach index 6.
- Pay 1 and climb one step to reach index 7.
- Pay 1 and climb two steps to reach index 9.
- Pay 1 and climb one step to reach the top.
The total cost is 6.

*Constraints:*

 - ~2 <= cost.length <= 1000~

 - ~0 <= cost[i] <= 999~
