WebOct 6, 2024 · Given an array, rotate the array to the right by k steps, where k is non-negative. Follow up: Try to come up as many solutions as you can, there are at least 3 different ways to solve this problem. WebIf you think some more, you'll see that "moving the first x elements to the back of an array of length y" is equivalent to "rotating by y - x". Substituting y = k and x = n%k , we need to rotate the first k elements by k' = k - n%k .
WebThe Boyer-Moore Majority Vote Algorithm is a widely used algorithm for finding the majority element in an array. The majority element in an array in C++ is an element that appears more than n/2 times, where n is the size of the array. The Boyer-Moore Majority Vote Algorithm is efficient with a time complexity of O (n) and a space complexity of ... WebJun 10, 2015 · You just have to iterate through the columns of the 2D array and rotate the values in each column. For up you need to (1) set value in first row (index (i) = 0) aside, (2) set value for row 1 (i = 0) = value for row 2 (i = 1), etc, using a loop, and (3) use the set-aside value to set last row. Or the other way round if you want to rotate down.
