Colin loves chicken strips. After searching far and wide, he has finally found the great chicken strip shrine!

The great chicken strip shrine contains a sorted line of infinite chicken strips where each chicken strip has a unique integer attached to it. To have a meal, Colin will choose to eat all the chicken strips in the range $[l,r]$. For example, if Colin was to eat all the chicken strips in the range $[-3,5]$, he would be eating chicken strips $[-3,-2,-1,0,1,2,3,4,5]$.

However, due to someone being a bit too hungry, the chicken strips between the range $[d,u]$ no longer exist. For example, if Colin was to eat the chicken strips in the range $[-3,5]$ but the chicken strips in the range $[-1,4]$ no longer exist, Colin would be eating chicken strips $[-3,-2,5]$.

The taste score of the meal is the product of the numbers of all the remaining chicken strips in the range $[l,r]$. For example, if the remaining chicken strips were $[-3,-2,5]$, the taste score would be $-3\times -2\times 5=30$.

Colin would like to know if the taste score of the meal is positive, negative, zero, or nonexistent. Please help build him a program to do this!

Constraints

For all subtasks:

$-{10}^{18}\le l\le r\le {10}^{18}$

$-{10}^{18}\le d\le u\le {10}^{18}$

Subtask 2 [80%]

No additional constraints.

Input Specification

The first line of input will contain space-separated integers $l$ and $r$, the lower and upper bound of the range of chicken strip values Colin would like to eat, respectively.

The next line of input will contain space-separated integers $d$ and $u$, the lower and upper bound of the range of chicken strips that no longer exist, respectively.

Output Specification

Let $x$ be the taste score of Colin's meal:

If $x>0$, print CHICKEN STRIP!!!. If $x=0$, print 0. If $x<0$, print -1. If $x$ does not exist, print burnt chicken nugget.

Sample Input 1

1 5
2 4

Sample Output 1

CHICKEN STRIP!!!

Explanation for Sample 1

The chicken strips in the range $[1,5]$ are $[1,2,3,4,5]$. If we exclude the chicken strips from $[2,4]$, we get $[1,5]$. The product of the leftover chicken strips is $5$ which is positive. Thus, print CHICKEN STRIP!!!.

Sample Input 2

-9 1
-6 0

Sample Output 2

-1

Explanation for Sample 2

The chicken strips in the range $[-9,1]$ are $[-9,-8,-7,-6,-5,-4,-3,-2,-1,0,1]$. If we exclude the chicken strips from $[-6,0]$, we get $[-9,-8,-7,1]$. The product of the leftover chicken strips is $-504$ which is negative. Thus, print -1.

Sample Input 3

-2 2
-2 2

Sample Output 3

burnt chicken nugget

Explanation for Sample 3

The chicken strips in the range $[-2,2]$ are $[-2,-1,0,1,2]$. If we exclude the chicken strips from $[-2,2]$, we get $[]$. The product of the leftover chicken strips does not exist because there are no leftover chicken strips. Thus, print burnt chicken nugget.
