// The majority element in an array is defined as the element that occurs more than n/2 times, // where n is the total number of elements. In the given test case {1, 2, 1, 3, 1, 2, 1, 3, 4, 4, 4}, // there is no element that satisfies this condition, making this test case invalid for the task // of finding a majority element. // // Additionally, the code has a critical flaw: it assumes that a majority element always exists. // It returns the element that ends up being the majority candidate at the end of the traversal, // but this candidate may not actually appear more than n/2 times in the array. // As a result, the code can produce incorrect results for arrays that do not contain a true majority element.
Oh shoot right I totally forgot about the > n/2 requirement!
