題目：Given two arrays of strings a1 and a2 return a sorted array r in lexicographical order of the strings of a1 which are substrings of strings of a2.例子：Example 1:a1 = ["arp", "live", "strong"]a2 = ["lively", "alive", "harp", "sharp", "armstrong"]returns ["arp", "live", "strong"]Example 2:a1 = ["tarp", "mice", "bull"]a2 = ["lively", "alive", "harp", "sharp", "armstrong"]returns []要求：要求實現function inArray(array1,array2){}測試用例：a2 = ["lively", "alive", "harp", "sharp", "armstrong"]
a1 = ["xyz", "live", "strong"]
Test.assertSimilar(inArray(a1, a2), ["live", "strong"])
a1 = ["live", "strong", "arp"]
Test.assertSimilar(inArray(a1, a2), ["arp", "live", "strong"])
a1 = ["tarp", "mice", "bull"]
Test.assertSimilar(inArray(a1, a2), [])
