// Java Linear Search Algorithm
// ----------------------------

/* 
   Time Complexity
     Best Time Complexity:O(1)
	 Average Time Complexity:O(n)
	 Worst Time Complexity:O(n)
     
   Space Complexity
     No auxiliary space is required in Linear Search implementation.
	 Hence space complexity is:O(1)

Step 1: Traverse the array
Step 2: Match the key element with array element
Step 3: If key element is found, return the index position of the array element
Step 4: If key element is not found, return -1
