It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company interview Questions. Max heap and min heap can be implemented using priority_queue in C++ STL. 15 The 1D array looks like a simple row here, and elements are stored one after another. Write a program in C# Sharp to insert New value in the array (unsorted list ). Click me to see the solution, 35. The graph will now contain many non-intersecting cycles. element - [1],[1] : 4 Sum of all elements stored in the array is : 15 element - 2 : 1 This article is contributed by Ayush Khanduri. 20 If all elements of the input array are the same, every element is a peak element. element - [1],[1] : 5 Input elements in the matrix : The first bin's range is [0, 31], second is [32, 63] and so on. Input the size of the square matrix : 2 The first matrix is : element - [0],[0] : 5 element - [0],[1] : 6 Test Data : Write a program in C# Sharp to find the second largest element in an array. Interview Preparation. element - [1],[0] : 3 1 2 Click me to see the solution, 22. Write a program in C# Sharp to sort elements of array in ascending order. 15 10 12 Input:arr[] = {20, 10, 8, 6, 4, 2}Output: arr[] = {20, 8, 10, 4, 6, 2}. Test Data : Insertion: process to insert an element in existing heap time complexity O(log N). Return index of element in original array arr(aux_array[position].second). Test Data : 7 8 9 Write a program in C# Sharp to find the second smallest element in an array. element - [2],[0] : -1 The matrix is an Identity Matrix. 16 Write a program in C# Sharp to find the sum of all elements of the array. Check if element is larger than largest value in sorted array; If larger: Move on; If smaller: Move item to correct position in sorted array; Details. Since we can find the median in O(n) time and split the array in two parts in O(n) time, the work done at each node is O(k) where k is the size of the array. 12 element - [0],[1] : 6 This can be easily done by visualizing the problem as a graph. Deletion: deleting the top element of the heap or the highest priority element, and then organizing the heap and returning the element with time complexity O(log N). Original array elements: element - [0],[0] : 1 In the end, the root of the Min-Heap is the required answer. To make any array a palindrome, we can simply apply merge operation n-1 times where n is the size of the array (because a single-element array is always palindromic, similar to single-character string). -2. element - [1],[0] : 4 element - 2 : 3 Click me to see the solution, 3.

Expected Output: Modified today. But in the case of the number of elements being large, the array in which we store the contiguous sums will run out of memory as the number of contiguous subarrays will be large (quadratic order), The key idea is to store the pre-sum of the array in a sum[] array. Input the number of elements to be stored in the array :5 See your article appearing on the GeeksforGeeks main page and help other Geeks. findMedian has the following parameter(s): int arr[n]: an unsorted array of integers ; Returns. element - [1],[1] : 8 Write a program in C# Sharp to accept a matrix and determine whether it is a sparse matrix. Input elements in the first matrix : The matrix is : Expected Output : Same as before, make a new array (called temp), which is the sorted form of the input array. Array [] : [a, a, b, b, c, c, d] Mathematical Equation = 2*(a+b+c+d) (a + a + b + b + c + c + d) As you see in the below code that in the function we pass the parameter array and as it is typescript we have also defined what type it is like " :Array
