10


Output

1024

Solution (in PYTHON3):

Solution:
n=int(input())
bi=bin(n)
bi=list(bi.strip())

bi=bi[2::]


if len(bi)<6:
    while(len(bi)<6):
        bi.insert(0,'0')

##print(bi)

bi[1],bi[5]=bi[5],bi[1]
bi[2],bi[3]=bi[3],bi[2]
##print(bi)
print(int(''.join(bi),2))

##and they lived hapily ever after
