Master HEAP: Understanding 4 patterns where HEAP data

WebSince our heap is actually implemented with an array, it would be good to have a way to actually create a heap in place starting with an array that isn't a heap and ending with an array that is heap. While it is possible to simply "insert" values into the heap repeatedly, the faster way to perform this task is an algorithm called Heapify. WebGiven an integer array, check if it represents min-heap or not. For example, the first array represents a min-heap, but the second array isn’t as it violate the heap property. Practice this problem Since the input is an array, the heap’s structural property (all levels except the last level are full) cannot be violated.
