A book store maintains the list of all its Books using XML. A Book consists of an ISBN number, which can be used as its attribute in the XML document. The following information is stored about the Book - book title, list of authors, name of the publisher and price of the Book. Create an XML document containing information of five Books. Also create the DTD to verify the XML document created by you

String Slicing

Given two strings

write a JS program to slice the inputString if it includes the subString. Slice the inputString starting from the subString to the end of the inputString.

Check Whether the input string includes the substring using if condition and includes().

if the input string includes the substring then, find the index of the substring in the input string, using the indexof() and store the index in a variable.

slice the input string, using the slice() form index to the length of the input string and store in the variable slicedString. console the variable sliceString.

If the input string doesn't include the substring then else console the input string.

Input

• The first line of input contains a string inputString
• The second line of input contains a string subString

Output

• The output should be a sliced string or inputString (if the inputString does not include the subString)

Unite Family: Given three objects father, mother, and child, write a JS program to concatenate all the objects into the family object using the spread operator.Input: The first line of input contains an object father, The second line of input contains an object mother

• The third line of input contains an object child

Output

• The output should be a single line string with the appropriate statement as shown in sample outputs

Constraints

• Keys of the objects should be given in quotes

Sample Input

{'surname' : 'Jones', 'city': 'Los Angeles'}

{'dish': 'puddings'}

{'pet': 'Peter'}

Sample Output

Mr and Mrs Jones went to a picnic in Los Angeles with a boy and a pet Peter. Mrs Jones made a special dish "puddings". Use spread operator to combine the input object to form a single object family. So that all the keys and values of father, mother, child will be in family object

String Slicing: Given two strings inputString and subString as inputs, write a JS program to slice the inputString if it includes the subString.Input: The first line of input contains a string inputString. The second line of input contains a string subString. Output: The output should be a sliced string or inputString (if the inputString does not include the subString)

.Follow the below approach to solve the String Slicing. Check Whether the input string includes the substring using if condition and includes().if the input string includes the substring then,Find the index of the substring in the input string, using the indexof() and store the index in a variable.slice the input string, using the slice() form index to the length of the input string and store in the variable slicedString. const slicedString = inputString.slice(index, inputString.length); console the variable sliceString.if the input string doesn't include the substring then else console the input string

Given two boolean values

isGrassTrimmerFound and isWaterHosePipeFound as inputs, create three JS promises using async/await and try/catch blocks.

Input

The first line of input contains a boolean isGrassTrimmerFound

The second line of input contains a boolean isWaterHosePipeFound

Sample Input 1

true

true

Sample Output 1

Grass Trimmed

Garden Cleaned

Watered Plants

Sample Input 2

true

false

Sample Output 2

Grass Trimmed

Garden Cleaned

Water Hose Pipe Not Found

Write a program for the Armstrong number

1. Write a program to print the sum of odd elements in the array

Given principal amount

principal as an input, time period in years time and appreciation percentage apprPercentage as optional inputs, write a JS function to return the final value finalValue with the given appreciation percentage and time period. The default values for time and apprPercentage are 2 and 5 respectively.

Quick Tip

The formula to calculate the final value with appreciation is,

finalValue = principal * (1 + time * appreciation / 100)
