PROBLEM:

Finding chef rating how much star chef rated is according to given rating pattern.

EXPLANATION:

Simply you have to check the condition but only need to keep in mind about open interval and close interval .
example:- if you encounter ( and ) means that number will not be include . but if you encounter [ or ] means include that number also in rating range.
Example–
[a,b]:- range is from a to b -> here a are enclosed by [ and b are enclosed by ] so in range both a and b will be include.
[a,b):- range is from a to b-1 -> here a are enclosed by [ and b are enclosed by ) so in range b will not be include.
(a,b):- range is from a-1 to b-1 -> here at a are enclosed by ( and b are enclosed by ) so in range both a and b will not be include.

SOLUTIONS:

Setter's Solution
import bisect
li=[1400,1600,1800,2000,2200,2500]
for i in range(int(input())):
    v=int(input())
    if(v>=0):
        print(bisect.bisect_right(li,v)+1)
Tester's Solution
 #include <stdio.h>

int main() {
int t;
scanf("%d", &t);

while(t--){
    int n,ans;
scanf("%d",&n);
if(n<1400)
    ans=1;
else if(n<1600)
    ans=2;
else if(n<1800)
    ans=3;
else if(n<2000)
    ans=4;
else if(n<2200)
    ans=5;
else if(n<2500)
    ans=6;
else
    ans=7;


    printf("%d\n",ans);

}


return 0;
