Palindromi

'''
my task is to take a string and output how many step it 
takes to turn it into a pallendrome.

ok so I feel like I can use 2 pointers
or just index.
this is my idea for a solution
for x in range(len(x)//2)
if (x)==len(x-1)
else 
 x+1 
return x


'''
x = input()
def program(x):
    j=0
    for i in range(len(x)//2):
        if x[i]!= x[len(x)-i]:
            
            j +=1
    return j
if __name__ == '__main__':
    print(program(x))
