Web1. Extract the Kth largest element from a sequence. 2. By selectively sorting the array to get Kth largest element it has the complexity of O (k*n). 2. We can improve the time complexity by approaching the problem using max-heap. 3. The time complexity is O (n+k*log (n)). Problem Solution 1. Approach the solution using max heap technique. 2. Webswap (H[1],H[i]): In each iteration of the loop, the first element of the array (which is the largest element in the heap) is swapped with the ith element of the array. This step moves the largest element to the end of the array. Heap size(H)-=1: After swapping the first element with the ith element, the size of the heap is reduced by 1.
