PROBLEM:
WWDC 2021 is announced……!
Total N companies have Participated in the WWDC 2021.As the total number of companies participated in the wwdc is more than expected.The organizers of the program decided to short list participants based on number of products each will showcase in wwdc.
Rule to get shortlisted for any company is that the company should showcase at least K Number of product in wwdc 2021.
You are given an array of size N i.e (Total number of companies). where each NiNi element denotes the total number of products that particular company will showcase. find out total number of companies that will be able to participate in wwdc 2021.
QUICK EXPLANATION:
Just Traverse the array and count all the elements greater than K.
and Print the Whole Number of Count That You Got while Traversing the array.
