Given the task is to find the maximum number of elements that can be made equal in a given array after incrementing its elements by at-most k times.Let’s now understand what we have to do using an example −Inputa[] = {1, 3, 8}, k = 4Output2ExplanationHere we can obtain two fours by incrementing 1 three times and incrementing 3 four times, that makes a[] = {4, 4, 8}Inputarr = {2, 5, 9}, k = 2Output0Approach used in the below program as followsIn main() function initialize int a[], size and k to store the array elements, size of array and the ...

Given the task is to find the maximum number of distinct lower case alphabets that are present between two upper case alphabets in the given string.Let’s now understand what we have to do using an example −Inputstr = “JKyubDoorG”Output3Explanation“yub” is present between the two upper case alphabets K and D which makes the count 3.“oor” is also present between the two upper case alphabets D and G which makes the count 2 as ‘o’ is a repeating alphabet and we are looking for distinct alphabets.Therefore, the output is 3.Inputstr = “ABcefsTaRpaep”Output4Approach used in the below program as followsIn function Max() ...

Given the task is to find a sub-string from a given binary string and then the maximum difference between the number of zeroes and the ones.Let’s now understand what we have to do using an example −Inputstr = “100100110”Output2ExplanationIn the sub-array from the position 1 to 5 (“00100”), the difference between the zeros and ones = 4 – 1 = 3 which is the maximum that can be found.Inputstr = “00000”Output5Approach used in the below program as followsIn main() function create a string str to store the binary string. Also initialize a variable int size to store the size of ... Read More

Given the task is to find a sub-string from a given binary string and then the maximum difference between the number of zeroes and the ones.Let’s now understand what we have to do using an example −Inputstr = “10010110”Output2ExplanationIn the sub-array from the position 1 to 4 (“0010”), the difference between the zeros and ones = 3 – 1 = 2 which is the maximum that can be found.Inputstr = “00000”Output5Approach used in the below program as followsIn main() function create a string str to store the binary string. Also declare an array int arr[str.length()+1];Set all elements of arr[] = ... Read More

Given the task is to find the maximum integer value that can be obtained while travelling in a path from the top left element to the bottom right element of a given square binary array, that is, starting from index [0][0] to index [n - 1][n - 1].While covering the path we can only move to right ([i][j + 1]) or to the bottom ([i + 1][j])The integer value will be calculate using the bits of the traversed path.Let’s now understand what we have to do using an example −Inputm = {    {1, 1, 1, 1},    {0, 0, ...

Given the task is to find the maximum count of substrings of length K consisting of same characters. Given a string s and another integer K, we have to count the occurrence of sub-strings of size K that have same characters.Out of the sub-strings that are found, we have to choose the sub-string occurring the maximum number of time.Let’s now understand what we have to do using an example −Inputs = ”tuuxyyuuc”, K = 2Output2ExplanationHere the sub-strings of length 2 and having same characters are: “uu” and “yy” but as it is seen that “yy” occurs only 1 time and ...

Given the task is to find the maximum number of threads that can be created within a process in C.A thread is lightweight process and can be independently managed by the scheduler. Because a thread is a component of a process, therefore multiple number of threads can be associated in a process and also it takes less time for context switching as it is lighter than the process.Threads require less resources than the processes and they also share memory with its peer threads. All user level peer threads are treated as a single task by the operating system. Less time ... Read More

A Globally Unique Identifier or GUID represents a gigantic identification number — a number so large that it is mathematically guaranteed to be unique not only in a single system like a database, but across multiple systems or distributed applications.The total number of unique keys (3.40282366×1038) is so large that the probability of the same number being generated twice is very small. For an application using 10 billion random GUIDs, the probability of a coincidence is approximately 1 in a quintillion.(1030)For example, in Retail domain if we want to generate a unique for each transaction so that a customer can ...

In C#, Dictionary is a generic collection which is generally used to store key/value pairs. In Dictionary, the key cannot be null, but value can be. A key must be unique. Duplicate keys are not allowed if we try to use duplicate key then compiler will throw an exception.As mentioned above a value in a dictionary can be updated by using its key as the key is unique for every value.myDictionary[myKey] = myNewValue;ExampleLet’s take a dictionary of students having id and name. Now if we want to change the name of the student having id 2 from "Mrk" to "Mark". Live ... Read More

Named parameters provides us the relaxation to remember or to look up the order of parameters in the parameter lists of called methods. The parameter for each argument can be specified by parameter name.NamedParameterFunction(firstName: "Hello", lastName: "World")Using named parameters in C#, we can put any parameter in any sequence as long as the name is there. The right parameter value based on their names will be mapped to the right variable. The parameters name must match with the method definition parameter names. Named arguments also improve the readability of our code by identifying what each argument represents.Example Live Demousing System; namespace ... Read More
