The program must accept a list of integers and Q queries as the input. For each query, the program must perform the operation based on the following conditions
- If the query type is 1, then the program must update the integers in the given range by adding the given value.
- If the query type is 2, then the program must print the sum of integers in the given range.

Your task is to define the class IntegerList so that the program runs successfully

The calling code Hello.py is as given below

from intergerlist import IntegerList
numList=IntegerList(list(map(int,input().strip().split())))
Q=int(input().strip())
for ctr in range(Q):
    query=input().split()
    queryType=int(query[0])
    if queryType==1:
        left,right,val=map(int,query[1:])
        numList.updateRange(left,right,val)
    elif queryType==2:
        left,right=map(int,query[1:])
        print(numList.getSum(left,right))

Example Input/Output 1: 
Input: 
10 20 30 40 50 60 
5 
1 2 4 5 
2 1 3 
1 1 6 -5 
2 1 6 
2 2 4 

Output: 
70 
195 
90 

Explanation:
 
The given list of integers are 10 20 30 40 50 60. 
Query 1: After updating the integers in the range(2, 4) by adding 5, the integers become 10 25 35 45 50 60. 
Query 2: The sum of integers in the range(1, 3) is 70 (10+25+35). 
Query 3: After updating the integers in the range(1, 6) by adding -5, the integers become 5 20 30 40 45 55. 
Query 4: The sum of integers in the range(1, 6) is 195 (5+20+30+40+45+55). 
Query 5: The sum of integers in the range(2, 4) is 90 (20+30+40). 

Example Input/Output 2: 
Input: 

12 10 10 10 15 15 15 10 12 
8 
1 1 4 -10 
2 1 4 
1 5 8 10 
2 5 8 
1 3 6 -20 
2 1 9 
1 1 9 5 
2 1 9 

Output:
 
2 
95 
29 
74



Solution;


class IntegerList:
    def __init__(self, integerList=[]):
        self.integerList=integerList 
        
    def updateRange(self,left,right,val):
        self.left=left
        self.right=right
        self.val=val 
        for i in range(left-1,right):
            self.integerList[i]=self.integerList[i]+val
            
    def getSum(self,left,right):
        self.left=left
        self.right=right
        s=0
        for i in range(left-1,right):
            s=s+self.integerList[i] 
        return(s)
