    how should I optimize my code, it is able to pass only two test cases and in rest time exceeded

    # Enter your code here. Read input from STDIN. Print output to STDOUT
import math
inp = list(map(int,input().split())) 
x=inp[0]
y=inp[1]
length = len(str(y))+1
total = 0
ls1 = set()
ls2 = set()
for i in range(1,x+1):
    for j in range(1,y+1):
        ls1.add((i*j*pow(10,length)))
        ls2.add(int(str(i^j).zfill(length)))
for i in ls1:
    for j in ls2:
        total = total+(i+j)
print(total)
