Here is a standard template to work with custom checker  

```
from __future__ import division
import json
from sys import stdin
 
def check_inputs (inputs, outputs):
    #inputs is a "list" of all input files. (Read carefully)
    lis = [] # lis is a 0/1 array which means 1 -> testcase success and 0-> test case failed
