Sum between two integers (두 정수 사이의 합)

Question

When two integers a and b are given, return the sum of integers between a and b.

For example, when a is 3 and b is 5, 3 + 4+ 5 = 12, then return 12.

 

Limitation

• If a and b are equal, return one of them.
• a and b is more than or equal to -10,000,000 and less than or equal to 10,000,000.
• a and b will be given regardless of size.

 

Example of I/O

a	b	return
3	5	12
3	3	3
5	3	12

 

My Solution

def solution(a, b):
    answer = 0
    if a == b:
        answer = a
    elif a < b:
        for x in range(a, b + 1):
            answer += x
    else:
        for x in range(b, a + 1):
            answer += x
    return answer
