    C :

    #include<stdio.h>
    char a[200];
    int pan(int a,int b);
    int main()
    {
    	scanf("%s",a);
    	int x=0;
    	for(;a[x]!='\0';x++);
    	int ans=x;
    	while(pan(0,x-1))
    	{
    		ans/=2;
    		x/=2;
    	}
    	printf("%d",ans);
    	return 0;
    }
    int pan(int m,int n)
    {
        int mid=(m+n)/2;
        for(int i=m;i<=mid;i++)
        if(a[i]!=a[n-i]) return 0;
        return 1;
    }
    

    Python :

    def huiwen(b):
        if b==b[::-1]:
            return 1
        else:
            return 0
    str1=input()
    while(huiwen(str1)):
        b=len(str1)
        str1=str1[0:int(b//2)]
    print(len(str1))
