+
+Problem -
+
+    Given an integer (numRows), return the first numRows of Pascal's triangle.
+
+    Pascal's triangle - each number is the sum of the two numbers directly above it 
+
+Example -
+
+    Input: n = 5
+
+    Output: [[1], [1, 1], [1, 2, 1], [1, 3, 3, 1], [1, 4, 6, 4, 1]]
+
+    Visualization:
+        1
+       1 1
+      1 2 1
+     1 3 3 1
+    1 4 6 4 1
+
+Time Complexity - O(n^2) n = number of rows
+
+Space Complexity - O(1) excluding the result array
