Describe Write a function, passing in an array of int, to return whether the array can be divided into two groups, so that the elements in the two groups are added together and equal, and that all multiples of 5 must be in one group, and all multiples of 3 in another group (not including a multiple of 5), can satisfy the above conditions, return True ; returns false when not satisfied.
