Given two integers `a` and `b`, which can be positive or negative, find the sum of all the numbers between including them too and return it. If the two numbers are equal return `a` or `b`.

**Note:** `a` and `b` are not ordered!

## Examples

```python
get_sum(1, 0) == 1   // 1 + 0 = 1
get_sum(1, 2) == 3   // 1 + 2 = 3
get_sum(0, 1) == 1   // 0 + 1 = 1
get_sum(1, 1) == 1   // 1 Since both are same
get_sum(-1, 0) == -1 // -1 + 0 = -1
get_sum(-1, 2) == 2  // -1 + 0 + 1 + 2 = 2
```
```C
get_sum(1, 0) == 1   // 1 + 0 = 1
get_sum(1, 2) == 3   // 1 + 2 = 3
get_sum(0, 1) == 1   // 0 + 1 = 1
get_sum(1, 1) == 1   // 1 Since both are same
get_sum(-1, 0) == -1 // -1 + 0 = -1
get_sum(-1, 2) == 2  // -1 + 0 + 1 + 2 = 2
```

Starter code:

def get_sum(a,b):
	

Solutions:
def get_sum(a,b):
    return sum(range(min(a, b), max(a, b) + 1))

def get_sum(a, b):
    return (a + b) * (abs(a - b) + 1) // 2

def get_sum(a,b):
    soma=0
    if a==b:
        return a
    elif a > b:
        for i in range(b,a+1):
            soma += i
        return soma
    else:
        for i in range(a,b+1):
            soma += i
        return soma

def get_sum(a,b):
    if a>b : a,b = b,a
    return sum(range(a,b+1))

# pseudo-code:
# test for equality

#
# if a greater than b
#    loop through the value of each number between b and a
#    accumulate each value in x

#    loop through the value of each number between a and b
#    accumulate each value in x

# return x
