WebAlso note that an element at index k occurs n times in subarrays of length 1 to n, and k times in bigger subarrays (till length N / 2 ). So the total number of occurrences in all subarrays upto length N / 2 is 1 + 2 +... + k + ( N / 2 − k) ∗ k = k ( N − k + 1) / 2. This result is replicated in subarrays of length greater than N / 2, so we ... WebGiven an array of N integers. Find the first element that occurs at least K number of times.
