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 1 [20%]

~-10 \le l \le r \le 10~

~-10 \le d \le u \le 10~

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.
