There are various applications of machine learning which are as follows −Social media services − Machine learning is an essential role in personalizing news feed to superior advertisement focusing over social media. Facebook needs machine learning to display news feed to the user based on its interests by treating items clicked earlier by that user.Facebook always takes note of the friends that it can linked with, the profiles that it can visit, interests, workplace, and on the basis of this continuous learning, a file of Facebook users are suggested for us to become friends with.The Face Recognition nature of Facebook ...

In this problem, we are given two arrays arr[] and del[]. Our task is to find the smallest after deleting given elements.We will be deleting values from the array arr[] that are present in del[]. And then print the smallest value after deletion.Let’s take an example to understand the problem, Input arr[] = {2, 5, 6, 9, 1} del[] = {1, 5, 9}Output 2Solution ApproachA simple solution to the problem is using hashing. We will insert all the values of del[] array in the hash table. Then we will traverse the array arr[] and check if the values in the ... Read More

In this problem, we are given a number N. Our task is to find the slope of the given number.Slope of a number is the total number of maxima and minima digits in the number.Maxima digit is the digit whose both neighbours (previous and next) are smaller.Maxima digit is the digit whose both neighbours (previous and next) are greater.Let’s take an example to understand the problem, Input N = 9594459Output 2Solution ApproachA simple solution to the problem is by traversing the number digit by digit from excluding the first and last one (the don’t count form maxima or minima). Now, ... Read More

In this problem, we are given a number K. Our task is to find the Minimum Fibonacci terms with sum equal to K.Fibonacci Series generates subsequent numbers by adding two previous numbers. The Fibonacci series starts from two numbers − F0 & F1. The initial values of F0 & F1 can be taken 0, 1 or 1, 1 respectively.Fibonacci Series is 0 1 1 2 3 5 8 13Let’s take an example to understand the problem, InputK = 5Output2ExplanationThe sum 5 can be made using 3 and 2.Solution ApproachBy using Fibonacci numbers we can get the sum as any number ...

In this problem, we are given an array arr[] consisting of N sorted integer values and an integer k. Our task is to Find the number of elements greater than k in a sorted array. Example Here are some examples of counting the array elements greater than the given target element: Input: arr = {6, 12, 16, 23, 32, 45, 48, 50} target = 20 Output: 5 Input: arr = {6, 12, 15, 20, 32, 45, 48, 50} target = 20 Output: 4 Finding number of elements greater than k in a sorted arrayHere is a list of ...

In this problem, we are given N ranges. Our task is to maximum occurred integer in n ranges.For the starting and ending value of all ranges. We need to find the value which occurs the most.Let’s take an example to understand the problem, Input S1 = 1, E1 = 3 S2 = 2, E2 = 6 S3 = 3, E3 = 4Output 2Solution ApproachA simple approach t o solve the problem is by using hashing, we will use a hash table to count all members and their count. We will traverse all ranges and store count in the hash table, ... Read More

In this problem, we are given an integer value N.Our task is to find the nth term of the series −14, 28, 20, 40, 32, 64, 56, 112….Let’s take an example to understand the problem, InputN = 6Output64Solution ApproachTo find the Nth term of the series we need to find the general term of the series. For which we need to observe the series closely. I can see two different ways to solve the series.Method 1The series is a mixture of two different series at even and odd positions.At odd positions − 14, 20, 32, 56, ….T1 = 14 T3 ... Read More

In this problem, we are given an integer value N. Our task is to use a C + + program to find the Nth Non Fibonacci Number.Fibonacci Series generates subsequent number by adding two previous numbers. The Fibonacci series starts from two numbers − F0 & F1. The initial values of F0 & F1 can be taken 0, 1 or 1, 1 respectively.Let’s take an example to understand the problem, Input N = 5Output 10Solution ApproachA simple solution to the problem is to find the Fibonacci numbers and then print the first n numbers which are not present in the ...
