+You are given an array A of N interger and an interger K.
+You want to remove K consecutive elements from A in such a way that the amplitude
+of the remaing elements will be minimal. 
+Here the amplitude is the difference between the maximal and the mimimal element.
+
+Examples:
+
+1.  A= [5,3,6,1,3]
+    K= 2
+    Output = 2
+
+    Here we can remove the 3rd and the 4th element to obtain the following array:
+    [5,3,3]. Hence the amplitude will be 5 - 3 = 2
+
+2.  A= [3, 5, 1, 3, 9, 8]
+    K= 4
+    Output = 1
+
+    Here we can remove the 1st, 2nd, 3rd,4th element to obtain the following array:
+    [9, 8]. Hence the amplitude will be 9 - 8  = 1
