Question on one of the test cases

Data Structures and Algorithms in Python
#1

for one of the test;
tests.append({
‘input’: {
‘cards’: [13, 11, 10, 7, 4, 3, 1, 0],
‘query’: 1
},
‘output’: 6
})
why is the output 6 and not 2.

#2

It doesn’t seem like correctly defined test case for this problem.

#3

This question is from the PythonDSA course Lecture 1 correct? The test case output gives the index of the query element from the cards list. Since the index of 1 in the cards list is 6 the output is 6.

Hi @adefowokea, here’s the definition we are using for rotating a list.

We define “rotating a list” as removing the last element of the list and adding it before the first element. E.g. rotating the list [3, 2, 4, 1] produces [1, 3, 2, 4].

Hope it helps!
