Solution (in PYTHON3):

Solution:
def dtb(n):  
    return bin(n).replace("0b", "")  
    
n = int(input())
c = list(dtb(n))
if(len(c) < 6):
    ld =6 -  len(c)
    for i in range(ld):
        c.insert(0,'0')
        
b = [0]*6
b[0] = c[0]
b[1] = c[5]
b[2] = c[3]
b[3] = c[2]
b[4] = c[4]
b[5] = c[1]

b = ''.join(b)
print(int(b,2))
