Hey! I was solving 2117C - Cool Partition and I find this peculiar thing in the testcase. It expects us to partition an array into segments such that every segment has same elements as first segment sort of. 4 ========== 1 2 1 1 ==========****

for this tc. I believe answer should be three as:

[1], [2, 1], [1] but answer is 2. Why?
