Bill studies in a school and he adores Maths. His class has been studying arithmetic expressions. On the last class the teacher wrote three positive integers `a`, `b`, `c` on the blackboard. The task was to insert signs of operations `+` and `*`, and probably brackets between the numbers so that the value of the resulting expression is as large as possible.

Possible variants:
- **a+b\*c=v1**
- **a\*(b+c)=v2**
- **a\*b\*c=v3**
- **(a+b)\*c=v4**

Note that you can insert operation signs only between `a` and `b`, and between `b` and `c`, that is, you cannot swap integers. For instance, in the given sample you cannot get expression **(a+c)\*b**.

Given an integers `a`, `b` and `c`. Return **maximum value of the expression** that you can obtain.

Find the maximum value of an expression formed by three integers using + and * operations.

Bob likes to play his game on paper. He writes `n` integers **a1, a2, ..., an**. Each of those integers can be either `0` or `1`. He's allowed to do exactly one move: he chooses two indices `i` and `j` **(1 ≤ i ≤ j ≤ n)** and flips all values `ak` for which their positions are in range `[i, j]` **(that is i ≤ k ≤ j)**. Flip the value of `ak` means to apply operation **ak = 1 - ak**.

The goal of the game is that after exactly one move to obtain **the maximum number of ones**.

Given a list of `0` or `1`. Return **the maximal number of 1s** that can be obtained after exactly one move.

Maximize the number of ones in a binary array after one flip operation.

One cozy afternoon, Lily and her friend Noah decided to buy a large cake from their favorite bakery. They chose the most decadent one, layered with rich frosting and fresh berries. After purchasing, the cake was weighed, showing a total weight of `n` grams. Excited to share it, they hurried home but soon realized they faced a tricky problem.

Lily and Noah are big fans of even numbers, so they want to divide the cake in such a way that each of the two portions weighs an even number of grams. The portions don’t need to be equal, but each must have a positive weight. Since they’re both tired and eager to enjoy the cake, you need to help them determine if it’s possible to split it the way they want.

Given an integer number `n` - the weight of cake bought by Lily and Noah, return a string `YES`, if Lily and Noah can divide the cake into two parts, each of them weighing an even number of grams and `NO` in the opposite case.

Determine if a cake can be split into two even-weight portions.
