Suppose we have a grid, there are few 0s and few 1s. We have to count the number of islands. An island is place that is surrounded by water and is formed by connecting adjacent lands horizontally or vertically. We can assume that all four edges of the grid are all surrounded by water.Suppose the grid is like −11000110000010000011There are three islands.To solve this, we will follow these steps −There will be two methods, one will be used to count number of islands called numIslands() and makeWater(). The makeWater() will be like −if number of rows in the grid is ... Read More
Suppose we have a binary tree, if we see the tree from right side, then we can see some elements of it. we have to display those elements. So if the tree is like −To solve this, we will follow these steps −We will create one helping method for dfs. This will take tree_node, an array to hold answers, and level. The level is initially 0. The dfs will work like below −if node is null, then returnif level = length of the answer array, then insert value of node into the ans arraydfs(right of the node, ans, level + ... Read More
Suppose we want to make one iterator for binary tree. There will be two methods. The next() method to return the next element, and hasNext() method to return Boolean value, that will indicate that the next element is present or not. So if the tree is like −And the sequence of function calls are [next(), next(), hasNext(), next(), hasNext(), next(), hasNext(), next(), hasNext()]. The output will be [3, 7, true, 9, true, 15, true, 20, false]To solve this, we will follow these steps −There are two methods next and hasNext, The next() method will be like −curr := stack top ...

Suppose we have an integer array called nums, we have to find the contiguous subarray within an array (containing at least one number) which has the largest product. So if the array is [2, 3, -2, 4], the output will be 6, as contiguous subarray [2, 3] has max product.To solve this, we will follow these steps −max_list := list of size nums, and fill with 0min_list := list of size nums, and fill with 0max_list[0] := nums[0] and min_list[0] := nums[0]for i in range 1 to length of numsmax_list[i] = max of max_list[i - 1]*nums[i], min_list[i - 1]*nums[i] and ...

In this tutorial, we will be discussing a program to find the largest element in an array.For this, we will be provided with an array. Our task is to find the largest number from the elements inside the array.Example Live Demo#include using namespace std; //finding largest integer int largest(int arr[], int n){ int i; int max = arr[0]; //traversing other elements for (i = 1; i < n; i++) if (arr[i] > max) max = arr[i]; return max; } int main(){ int arr[] = {10, 324, 45, 90, 9808}; int n = sizeof(arr) / sizeof(arr[0]); cout
In this tutorial, we will be discussing a program to find if a character is a vowel or consonant.For this, we will be provided with a character. Our task is to print out to the user whether the provided character is a vowel or a consonant.Example Live Demo#include using namespace std; //checking if the character is a vowel or consonant void is_vowel(char x){ if (x == 'a' || x == 'e' || x == 'i' || x == 'o' || x == 'u') cout
In this tutorial, we will be discussing a program to find HCF iteratively.For this, we will be provided with two numbers. Our task is to calculate the HCF of the given numbers using an iterative function.Example Live Demo#include using namespace std; int get_HCF(int a, int b){ while (a != b){ if (a > b) a = a - b; else b = b - a; } return a; } int main(){ int a = 60, b = 96; cout
In this tutorial, we will be discussing a program to find N-th term of series 3, 5, 33, 35, 53…For this, we will be provided with a number. Our task is to find the term for the given series at that particular position.Example Live Demo#include using namespace std; //finding the nth term in the series int printNthElement(int n){ int arr[n + 1]; arr[1] = 3; arr[2] = 5; for (int i = 3; i
Consider the below example, we have created Advanced function to get the specific process information like Process Name, Process ID (PID), Start Time, Responding status, etc.function Get-ProcessInformation{ [cmdletbinding()] param( [Parameter(Mandatory=$True)] [string[]]$name ) Begin{ Write-Verbose "Program started" } Process{ Write-Verbose "Extracting Process Inforamtion" Get-Process $name | Select Name, ID, StartTime, Responding | ft - AutoSize } End{ Write-Verbose "Function ends here" } }Above is the advanced function example. When we run the above command, it will give ... Read More
AllowEmptyString() attribute works with the string variable and AllowEmptyCollection() work with the array of different data types (Collection).Consider the example below. Here, we are using a mandatory variable $name which is a string and $stringarray which is a string array.function print_String{ [cmdletbinding()] param( [parameter(Mandatory=$True)] [string]$name, ) Write-Output "Writing a single string" $name }If we get the output of the above variable it will generate an error below.PS C:\WINDOWS\system32> print_String cmdlet print_String at command pipeline position 1 Supply values for the following parameters: name: print_String : Cannot bind argument to ...
