Given with a decimal number as an input, the task is to convert the given decimal number into a binary number.Decimal number in computers is represented with base 10 and binary number is represented with base 2 as it has only two binary digits 0 and 1 whereas decimal numbers can be any numeric digit starting from 0 – 9.To convert a decimal number into a binary number follow the given steps −Firstly divide the given number with the base value of conversion number e.g. dividing 42 by 2 because we need to convert 42 into a binary numbers which ...

Given with a binary number as an input, the task is to convert the given binary number into a decimal number.Decimal number in computers is represented with base 10 and binary number is represented with base 2 as it has only two binary digits 0 and 1 whereas decimal numbers can be any numeric digit starting from 0 – 9.To convert a binary number into a decimal number we will extract digits starting from right to left through a remainder and then multiply it with the power of 2 starting from 0 and will be increased by 1 till the ...

Given with the input as an IP address value and the task is to represent the given IP address as its hexadecimal equivalent.What is IP addressIP address or Internet protocol is a unique number to that uniquely describes your hardware connected to a network. Internet means over the network and protocol defines the set of rules and regulations that must be followed for connection. Because of IP address only it is possible for a system to communicate with another system over a network. There are two versions of IP that are −IPv4(Internet Protocol Version 4)IPv6(Internet Protocol Version 6)IP address is ... Read More

Given with the input as KiloBytes and the task is to convert the given input into number of bytes and bits.Bit − In computers, bit is the smallest unit represented with two integer value 0 and 1 and all the information in computer is processed as a sequence of these two digits.N-bits = 2 ^ N patterns, where N can be any integer value starting from 1.Byte − In computers, byte is represented with 8 bits. Byte is capable of holding one character to numbers ranging between 0 and 255.1 byte = 8 bitsWhich means 2 ^ 8 patterns which ... Read More

You are given with number of days, and the task is to convert the given number of days in terms of years, weeks and days.Let us assume the number of days in a year =365Number of year = (number of days) / 365Explanation-: number of years will be the quotient obtained by dividing the given number of days with 365Number of weeks = (number of days % 365) / 7Explanation-: number of weeks will be obtained by collecting the remainder from dividing the number of days with 365 and further dividing the result with number of days in a week ...

Given with the matrix of size nxn the task it to convert any type of given matrix to a diagonal matrix.What is a diagonal MatrixDiagonal matrix is the nxn matrix whose all the non-diagonal elements are zero and diagonal elements can be any value.Given below is the diagram of converting non-diagonal elements to 0.$$\begin{bmatrix}1 & 2 & 3 \4 & 5 & 6 \7 & 8 & 9 \end{bmatrix}\:\rightarrow\:\begin{bmatrix}1 & 0 & 3 \0 & 5 & 0 \7 & 0 & 9 \end{bmatrix}$$The approach is to start one loop for all non-diagonal elements and another loop for diagonal elements ...

The Jackson @JacksonInject annotation can be used to inject the values into parsed objects instead of reading those values from the JSON. In order to inject values into a field, we can use the InjectableValues class and need to configure the ObjectMapper class to read both the injected values from the InjectableValues class and the remaining values from the JSON string.Syntax@Target(value={ANNOTATION_TYPE, METHOD, FIELD, PARAMETER}) @Retention(value=RUNTIME) public @interface JacksonInjectExampleimport com.fasterxml.jackson.annotation.*; import com.fasterxml.jackson.databind.*; import java.io.*; public class JacksonInjectTest {    public static void main(String args[]) throws IOException {       String jsonString = "{\"empName\": \"Raja Ramesh\"}";       InjectableValues injectableValues = new InjectableValues.Std().addValue(int.class, 110); ...

Suppose we two integers N and P. The P is the product of N unknown integers. We have to find the GCD of those integers. There can be different groups of integers possible, that will give the same result. Here we will produce GCD, which is maximum among all possible groups. Suppose N = 3, and P = 24, then different groups will be like {1, 1, 24}, {1, 2, 12}, {1, 3, 8}, {1, 4, 6}, {2, 2, 6}, {2, 3, 4}. The GCDs are: 1, 1, 1, 1, 2, 1. So answer is 2 here.The technique us like, ... Read More

Suppose we have a binary string of length n, another value say k is given. We have to concatenate the binary string k times. Then we have to find the maximum number of consecutive 0s in the concatenated string. Suppose binary string is “0010010”, and k = 2, then after concatenating the string k times, it will be “00100100010010”. So the maximum number of consecutive 0s is 3.The approach is simple. If the number has all 0s, then the answer will be n * k. If the string contains ones, then the result will be either the max length of ... Read More
