Given a binary array consisting of only 0s and 1s, find the maximum distance between two elements with value 0 in a subarray {l,r}. Examples: Input : arr = {1,0,0,1}, l=0, r=3 Output : 1 Clearly, in the range from 0 to 3, first 0 lies at index 1 and last at index 2. Hence, the distance 2-1… Read More »
C++ is Object-Oriented Programming (OOP) language. C++ is easy to understand. You can learn C++ by following these steps: Writing your program in a text editor. Then saving it with the appropriate file extension (e.g., .cpp, .c, .cp). Compiling your program using a compiler or an online Integrated Development Environment (IDE). Understanding of the basic terminologies. Writing First… Read More »
In C/C++, the fork() function is used to generate a new process known as the child process. We can do searching within a fork() process. Problem statement – Write a program to search the key element in parent process and print the key to be searched in child process. Examples: Input : Key=7; array[5] = { 2, 5,… Read More »
C++ is programming language. It is object-oriented, and generic programming paradigms. C++ is compatible with multiple platforms such as Windows, Linux, Unix, and Mac. Using Online IDE Before starting C++ programming, it is necessary to set up an environment on your local computer to compile and execute C++ programs. You can also use Online Integrated Development Environments (IDEs)… Read More »
Given a multi-set of n integers. We have to select exactly k of them in a such way that the difference between any two of them is divisible by m, if it is not possible we will simply return “no” and if it is we will print yes. Examples: Input : 3 2 3 //n,k,m respectively 1 8… Read More »
Given an array of n elements and we have to find the standard deviation of numbers. Examples: Input : arr[] = {9, 2, 5, 4, 12, 7, 8, 11, 9, 3, 7, 4, 12, 5, 4, 10, 9, 6, 9, 4} Output : 2.983 Input : arr[] = {10, 5, 4, 7, 9, 34, 16, 23, 28} Output… Read More »
Given N = no of rows and M = no of columns, print the hollow pattern. ********** * * * * * * ********** Given above is an example of hollow pattern of 5 x 10. Given below is the approach to built hollow pattern: To iterate through rows, run an outer loop from 1 to rows. Define… Read More »
Given a Singly Linked List. The task is to check if the characters in a node is vowel if yes then toggle the case of the vowel. Examples: Input : C-> p-> l-> u-> s-> p-> l-> u-> s Output : C p l U s p l U s The nodes with vowels are ‘u’ toggle the… Read More »
Write a program to validate whether the brackets in the given input string are balanced or not. Examples: Input : {[()]} Output : Valid Input :{{(}}[] Output : Invalid Explanation: This problem is a very common application of stacks in data structures. An opening bracket may be ‘{‘,'[‘,'(‘ and their corresponding closing brackets are ‘}’,’]’,’)’. The brackets are… Read More »
In this technological and digital age where everything is automated. We should prefer something which saves time and space and makes our work easy. Lucky for us C++ programmers, we have switch case statements. It is a great alternative to the If else condition statement. It reduces the amount of code to a very small size which saves… Read More »
