WebWe can find the majority element using linear time and constant space using the Boyer–Moore majority vote algorithm. The algorithm can be expressed in pseudocode as the following steps: Initialize an element m and a counter i = 0 for each element x of the input sequence: if i = 0, then Web• Get the middle element of the array by dividing the size of the index by two and then perform the ceiling function and then assign it to the variable “mid”. • Get the majority element of the left array and right array by calling the same function majority by passing half of the array. • Then, check whether both the elements are equal.
