+# Task 2: Target Array
+# ====================
+#
+# You are given two arrays of integers, @source and @indices. The @indices can
+# only contains integers 0 <= i < size of @source.
+#
+# Write a script to create target array by insert at index $indices[i] the
+# value $source[i].
+#
+## Example 1
+##
+## Input: @source  = (0, 1, 2, 3, 4)
+##        @indices = (0, 1, 2, 2, 1)
+## Output: (0, 4, 1, 3, 2)
+##
+## @source  @indices  @target
+## 0        0         (0)
+## 1        1         (0, 1)
+## 2        2         (0, 1, 2)
+## 3        2         (0, 1, 3, 2)
+## 4        1         (0, 4, 1, 3, 2)
+#
+## Example 2
+##
+## Input: @source  = (1, 2, 3, 4, 0)
+##        @indices = (0, 1, 2, 3, 0)
+## Output: (0, 1, 2, 3, 4)
+##
+## @source  @indices  @target
+## 1        0         (1)
+## 2        1         (1, 2)
+## 3        2         (1, 2, 3)
+## 4        3         (1, 2, 3, 4)
+## 0        0         (0, 1, 2, 3, 4)
+#
+## Example 3
+##
+## Input: @source  = (1)
+##        @indices = (0)
+## Output: (1)
