+ * which will only contain two strings of equal length that represent binary numbers,
+ * and return a final binary string that performed the bitwise OR operation
+ * on both strings.
+ * ---
+ * A bitwise OR operation places a 0 in the new string
+ * where there are zeroes in both binary strings,
+ * otherwise it places a 1 in that spot.
+ * ---
+ * For example: if strArr is ["1001", "0100"] then your program
+ * should return the string "1101"
