This is left rotating array.Why it is not appending correctly, basically in first iteration it should append 3,4,5,1,2

Question

Example input
A = [1, 2, 3, 4, 5]
B = [2, 3]

Output:
[ [3, 4, 5, 1, 2]
[4, 5, 1, 2, 3] ]

def reverse(a,left,right):
#print(a)
while right>left:
a[left],a[right]=a[right],a[left]
left+=1
right-=1
#print(a)
return a
class Solution:
def solve(self, A, B):
res=[]
l=len(A)
d=A
for i in range(len(B)):
# print(i)
mod=B[i]%l
# print(A)
# print(d)
reverse(d,mod,l-1)
reverse(d,0,mod-1)
reverse(d, 0, l-1)
res.append(d)
return res

Answer 1

for n in B:
C=A[::]
for _ in range(n):
C.push(C.pop())
print(C)

Could be near to what u need

Answer 2

Does it rotate or swap?

Answer 3

What is A and B?
