What is a code to binary Indexed Tree : Range Updates and Point Queries and the other steps required given the following:
Binary Indexed Tree : Range Updates and Point Queries | Updates such that getElement ( ) gets an increased value when queried from l to r ..
Get the element indexed at i.
To get ith element sum of all the elements from 0 to i need to be computed.
Driver Code.
Find the element at Index 4.
Find the element at Index 3"

#Here is code to binary Indexed Tree : Range Updates and Point Queries and the other steps required.
 def update ( arr , l , r , val ) :
	arr [ l ] += val
	if r + 1 < len ( arr ) :

def getElement ( arr , i ) :
	res = 0
	for j in range ( i + 1 ) :
		res += arr [ j ]
	return res

	arr = [ 0 , 0 , 0 , 0 , 0 ]
	n = len ( arr )
