Search Item in a Mart

Given an array 

mart of objects in the prefilled code and categoryOfItem, item as inputs, create a JS promise,

resolve with "Item Found" text, if the 

categoryOfItem matches with the category and the corresponding items list includes the item

reject with "Category Not Found" text, if the 

categoryOfItem does not match with any catergory in the mart

reject with "Item Not Found" text, if the 

items list does not include item

Use async/await and try/catch blocks.

Quick Tip
You can use array methods find() and includes().
Input
The first line of input contains a string categoryOfItem
The second line of input contains a number item
Output
The output should be a single line string with the appropriate message
Sample Input 1
pulses
green gram
Sample Output 1
Item Found

Sample Input 2
detergents
tide
Sample Output 2
Category Not Found

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

inputString and subString as inputs, 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.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)

Series of Operations

Given an array

1. myArray of numbers, write a JS program to perform the following steps and log the result. Multiply each value with 9.
2. Subtract 20 from each value.
3. Multiply each value with 7.
4. Log the values of the resulting array separated by a space.

Input

• The input will be a single line containing an array myArray

Output

• The output should be a single line with values separated by a space

Constraints

• Each value in the array must be a number

Sample Input

[ 12, 2, 2, 4, 1 ]

Sample Output

616 -14 -14 112 -77

Split and Replace

Given three strings

inputString, separator and replaceString as inputs. Write a JS program to split the

inputString with the given separator and replace strings in the resultant array with the replaceString whose length is greater than 7.

Quick Tip

• You can use the string method split()
• You can use the array method map()

Input

• The first line of input contains a string inputString
• The second line of input contains a string separator
• The third line of input contains a string replaceString

Output

• The output should be a single line containing the strings separated by a space

Area and Circumference of a Circle

Given radius

radius of a circle, write a JS constructor function with the methods getArea and getCircumference to calculate the area and circumference of the circle.

Note

The value of π = 3.14

Quick Tip

Use the formulae to calculate,

• Area of circle = π * radius * radius
• Circumference of circle = 2 * π * radius

Input

• The input will be a single line containing a number radius

Output

• The first line of output should contain the area of the circle
• The second line of output should contain the circumference of the circle

A Hotel is offering discounts to its customers.

Given charge per day

dayCharge based on category and numbers of days customer stayed days as inputs, write a JS arrow function to return the total bill with the discount.

Quick Tip

• The formula for bill is,
• bill = dayCharge * days
• The formula to calculate the discounted bill,
• bill - (bill * discount) / 100

Apply discounts on the following basis,

• 5%, if the customer stays more than 2 days
• 15%, if the customer stays more than 5 days

Input

• The first line of input contains a number dayCharge
• The second line of input contains a number days
