Explanation

Test Case 11: The problem is worth 1010 points and since there are 1010 test cases, each test case is worth 11 point. Since Chef passes 33 test cases, his score will be 13=31⋅3=3 points.

Test Case 22: The problem is worth 100100 points and since there are 1010 test cases, each test case is worth 1010 points. Since Chef passes all the 1010 test cases, his score will be 1010=10010⋅10=100 points.

Test Case 33: The problem is worth 130130 points and since there are 1010 test cases, each test case is worth 1313 points. Since Chef passes 44 test cases, his score will be 134=5213⋅4=52 points.

Test Case 44: The problem is worth 7070 points and since there are 1010 test cases, each test case is worth 77 points. Since Chef passes 00 test cases, his score will be 70=07⋅0=0 points.
