Array Contains

Given an array of integers nums and another integer value, check if value occurs in nums.

If the value occurs in nums, return true; otherwise return false.

Examples:

contains([]int{1, 2, 4, 5}, 4) -> true

contains([]int{-1, 2, -4, 0, 10}, 7) -> false

Note:

Do not use builtin functions such as slices.Contains(), it would defy the purpose of the challenge. Write the whole code yourself.
