Given a sting of a big number say num and another big number say m; the task is to print the quotient using divide operation and the remainder of the big number using modulus.The output should be Remainder = xxx; Quotient = yyyLet’s assume we have an input num = string num = "14598499948265358486" and other input m = 487 so the remainder is 430 and quotient is 29976385930729688.ExampleInput: num = “214755974562154868”    m = 17 Output: Remainder = 15    quotient = 12632704386009109 Input: num =“214”    m = 5 Output: Remainder = 4    Quotient = 42Approach we ...

The @JsonAdapter annotation can be used at field or class level to specify the Gson. The TypeAdapter class can be used to convert Java objects to and from JSON. By default, Gson library converts application classes to JSON by using built-in type adapters but we can override it by providing custom type adapters.Syntax@Retention(value=RUNTIME) @Target(value={TYPE, FIELD}) public @interface JsonAdapterExampleimport java.io.IOException; import com.google.gson.Gson; import com.google.gson.TypeAdapter; import com.google.gson.annotations.JsonAdapter; import com.google.gson.stream.JsonReader; import com.google.gson.stream.JsonWriter; public class JsonAdapterTest {    public static void main(String[] args) {       Gson gson = new Gson();       System.out.println(gson.toJson(new Customer()));    } } // Customer class class Customer { ...

Given a number n in form of a string; the task is to print that following number in large using hash symbols.Like we have provided a number “1234”The representation of the following number should be −Likewise we want our solution to be printed −ExampleInput: n[] = {“2234”} Output:Input: n[] = {“987”} Output:Approach we will be using to solve the given problem −Take at most 4 digit number a input in a string.Make arrays of every number one by one the large pattern we want for the number.Traverse the string and print every number one by one.AlgorithmStart    Step 1 -> ...

Given a number as a string and a base; the task is to check whether the given number of is of that given base or not.We have to check the number and the base according to the number system in which there are bases like 2 for a binary number, 8 for an octal number, 10 for decimal number and 16 for a Hexadecimal number. According to this we have to find whether the given number in a string belongs to a particular base or not, If it belongs to a particular base then we have to print “Yes” on ... Read More

Given ‘a’ the First term, ‘d’ the common difference and ‘n’ for the number of terms in a series. The task is to find the nth term of the series.So, before discussing how to write a program for the problem first we should know what is Arithmetic Progression.Arithmetic progression or arithmetic sequence is a sequence of number where the difference between the two consecutive terms is same.Like we have first term i.e a =5, difference 1 and nth term we want to find should be 3. So, the series would be: 5, 6, 7 so the output must be 7.So, ... Read More

Given ‘a’ the First term, ‘r’ the common ratio and ‘n’ for the number of terms in a series. The task is to find the nth term of the series.So, before discussing how to write a program for the problem first we should know what is Geometric Progression.Geometric progression or Geometric sequence in mathematics are where each term after the first term is found by multiplying the previous one with the common ratio for a fixed number of terms.Like 2, 4, 8, 16, 32.. is a geometric progression with first term 2 and common ratio 2. If we have n ... Read More

Given an Url address of any website; the task is to calculate the round trip time of a website.Round Trip Time(RTT) is the total time or the length of a time which is taken to send a signal plus the time taken to receive the acknowledgement of that signal to be received. This time also consist of the propagation times between two points of a signal.An end user can determine his/her round trip time from an IP address by pinging that address.The Round Trip time’ result depends upon the following reasons −The Transmission medium.The presence of Interface in the circuit.Number ...

Given RGB color range in form of integers; the task is to find its appropriate HSV color by converting the RGB color rangeWhat is RGB color modelRGB color model comprised of three colors Red, Green and Blue. RGB model is a color model which is widely used in the display technologies; it is an additive model in which we add these three colors of with different intensities to produce millions of different colors on a display device.What is HSV color model?HSV color model comprises Hue, Saturation, Value also known as HSB (Hue, Saturation, Brightness).HSV is alternative representation of RGB color ...

Given a string consisting of numerical values, the task is to covert those given numbers in words.Like we have an input “361”; then the output should be in words i.e, ” Three hundred sixty one”. For the solution of the following problem we have to keep in mind the numbers and places it is in on like ones, tens, thousands etc.The code only support upto 4 digits numbers i.e., 0 to 9999. So the input should be from 0 to 9999.Let us consider 1, 111 so the places will be like −ExampleInput: “1234” Output: one thousand two hundred thirty four ... Read More

Given a positive integer n we have to print all the subsets of a set of {1, 2, 3, 4, … n} without using any array or loops.Like we have given any number say 3 s we have to print all the subset in the set {1, 2, 3} which would be {1 2 3}, {1 2}, {2 3}, {1 3}, {1}, {2}, {3} { }.But we have to do this without using any loop or an array. So, only the recursion is the possible way to solve this type of problem without using any array or a loop.ExampleInput: 3 ... Read More
