IN JAVA Given an array of numbers, return whether it is possible to make the number 7 by adding any three different numbers together. Examples luckySeven ([2, 4, 3, 8, 9, 1]) → true luckySeven ([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]) → true luckySeven ([0, 0, 0, 2, 3]) → false // You cannot repeat the same number to make 2 + 2 + 3 = 7 luckySeven ([4,, 3])→ false // You need three different numbers.
