Round-2 : DSA and Problem Solving Round

The Interviewers were very humble and friendly. They asked about my past projects and company briefly to make me comfortable.
They asked following two question -

a) We have given an array of height of balloon and unlimited arrows to burst all balloons and we are using arrows from the left side of the array only.
If you target a balloon then same arrow can burst the balloon (should be in right side of the targeted ballon ) which is strictly less than 1 in height from the targeted ballon.
We have to find minimum arrows to burst all the bollons.

	   Input - [5,3,4,2,1]
	   answer - 2
	   Explanation - One arrow for bursting 5,4 and second arrow will but 3,2,1. So answer would be 2.
	   
	   Input - [1,2,3,4,5]
	   answer - 5
	  

They are expecting the approach with complexity - O(n)
