+# TASK #1 › Min Sliding Window
+# You are given an array of integers @A and sliding window size $S.
+
+# Write a script to create an array of min from each sliding window.
+
+# Example
+# Input: @A = (1, 5, 0, 2, 9, 3, 7, 6, 4, 8) and $S = 3
+# Output: (0, 0, 0, 2, 3, 3, 4, 4)
+
+# [(1 5 0) 2 9 3 7 6 4 8] = Min (0)
+# [1 (5 0 2) 9 3 7 6 4 8] = Min (0)
+# [1 5 (0 2 9) 3 7 6 4 8] = Min (0)
+# [1 5 0 (2 9 3) 7 6 4 8] = Min (2)
+# [1 5 0 2 (9 3 7) 6 4 8] = Min (3)
+# [1 5 0 2 9 (3 7 6) 4 8] = Min (3)
+# [1 5 0 2 9 3 (7 6 4) 8] = Min (4)
+# [1 5 0 2 9 3 7 (6 4 8)] = Min (4)
