Sum by Type

You have an array. Each value from that array can be either a string or an integer. Your task here is to return two values. The first one is a concatenation of all strings from the given array. The second one is a sum of all integers from the given array.

**Input: ** A list of strings and ints

**Output: ** An array

**Example:**

sumByTypes([]) == ['', 0] sumByTypes([1, 2, 3]) == ['', 6] sumByTypes(['1', 2, 3]) == ['1', 5] sumByTypes(['1', '2', 3]) == ['12', 3] sumByTypes(['1', '2', '3']) == ['123', 0] sumByTypes(['size', 12, 'in', 45, 0]) == ['sizein', 57]

**How it’s used: **
*(math is used everywhere)*

**Precondition:**
*both given ints should be between -1000 and 1000*
