This can be achieved by using comments in the program. Flowcharts and Algorithms are not required. The programs must be written in Java.) Questio: Write a menu [10 driven program a program to initialize ()Display the second 1D array ot size and do the following I71 them highest without sorting the array array 7 Rearranged Array: A number is unique or not. an minimum element in tha array and swap Find the maximum and Example: Initialize (using wcikeh case) to check: A number is disarium or not. 2 Write 7 85 25 45 78 40 25 45 78 85 40 Second highest: 78 [A number is said to be disarium if sum of its digits powered with their respective position is equal to the original number. For example 89 as 8'+92 89. A numberis said to be unique if the digits are not duplicate. For example, Question : Write a program to input number of units consumed by 5) a customer. Calculate and display the bill amount on the basis of the iollowing: 20, 56, 9863, 145] Taritf Table: Number of Unit Rate per unit Write a program to input row size, column size and the elements of a 2D array. Display all the tech numbers present in this array with the coresponding row and column index. First 100 units Rs 10.00 Next 200 units Rs.12.00 [A tech number has even number of digits. If the number is split in two equal halves, then the square of sum of these halves is equal to the number itself. Above 300 units Rs. 15.00D Question6 [8 Example A surcharge of 2.5% wilf be charged it the number ot units consumed is above 300 units. Consider the number 3025 Square of sum of the halves of 3025 =(30+25) (55) 3025 is a tech number.] Subject: Computer Science (Paper 1, Theory) Class XI 2022-2023 Subject: Computer Science (Paper 1, Theory) Class 0220I
