Write a Java program to find continuous sub array of the given array whose sum is equal to a given number. For example, If {12, 5, 31, 9, 21, 8} is the given array and 45 is the given number, then you have to find continuous sub array in this array such that whose elements add up to 45. In this case, {5, 31, 9} is such sub array whose elements add up to 45.
Write in Java.
Write a function to read elements of a N by N, 2 dimensional (2D) array and display the 2D array in a matrix form and find the first row and column with the most 1s.
Input: 4
0 0 1 1
0 0 1 1
1 1 0 1
1 0 1 0
Where,
First line of represents n, the number of rows and columns.
Second line contains array elements of the 1st row and so on.
Output:
0 0 1 1
0 0 1 1
1 1 0 1
1 0 1 0
2
2
where,
There must be single space between 2 numbers in the row.
There should not be any space after the last number in the row. e.g. in the last row, there should not be any space after number 0.
The first number bellow the matrix is the index of the first row with the most 1s and the second number is the index of the first column with the most 1s.
There should not be any space after the second number (the index of the first column with the most 1s).
Assume that,
Row and column values are integers within the range [1 to 100].
2D Array elements are within the range [0 to 1].
Write a Java program using a one-dimensional array that accepts as input an integervalue asking for the number of elements for each list. This will be used to generate randomnumbers (5 to 69) for the one-dimensional arrays (List A and List B). The program willcompute for the product and store it in another array (List C).

- Write a program in java that prompts the user to enter an inte- ger m and find the smallest integer n such that m * n is a perfect square. (Hint: Store all smallest factors of m into an array list. n is the product of the factors that appear an odd number of times in the array list. For example, consider m = 90, store the factors 2, 3, 3, and 5 in an array list. 2 and 5 appear an odd number of times in the array list. Thus, n is 10.)arrow_forwardWrite a program in java using two dimensional arrays. You should prompt the user toenter the number of rows and columns for your matrix. You should then prompt the userto enter values for each element of the matrix. Once the user has provided all the values for matrix, you should print the matrix and transpose of that matrix. A transpose of a matrix converts rows to columns and columns to rows.Example:Output: This program transposes a matrix.Output: Please enter the number of rows:User enters 2Output: Please enter the number of columns:User enters 3Enter value for row[0] column[0]: 9Enter value for row[0] column[1]: 1Enter value for row[0] column[2]: 2Enter value for row[1] column[0]: 72Enter value for row[1] column[1]: 3Enter value for row[1] column[2]: 6The matrix you entered is:9 1 272 3 6The transpose of this matrix has 3 rows and 2 columns and the transpose is:9 721 32 6arrow_forwardWrite a program in java using two dimensional arrays.

- Write a C program that reads in an array of integers of size n (n <= 100) from the user and prints out the largest subarray of consecutive integers in the array. For example, if the user enters the array [3, 4, 5, 1, 2, 3, 6, 7], the program should output "Largest subarray of consecutive integers: [3, 4, 5]".arrow_forward. Implement a program that randomly generates 10 integers from -100 to 100, stores them in a 1D array, and finds their maximum value. Calculate the execution time of finding a maximum. Repeat the test for 10,000 and 10,000,000 numbers. Provide your results in the form of a table below and provide a small summary. Implement a Java program that will populate a 5x5 matrix with randomly generated integers from 0 to 100. (1) print your matrix in a table form. (2) modify your code to multiply all even numbers by 10 and print the matrix. Your output of questions (1) and (2) should match the format of the following sample outputs:arrow_forwardWrite a program that reads an integer array a[] from the console and writes out the subsequence of the array that sums to the largest value. If there are more than one such subsequence, then the program should write out the subsequence that starts at the smallest position in the array and, if there are more than one subsequence of largest sum starting at the same smallest position, it should write out the shortest such subsequence.arrow_forward
- Implement the vacuum cleaning agent function in Python/Java for the scenario described below: Consider two-dimensional Boolean array of size m x n (m and n can each be equal to 4) where m is the number of rows, and n is the number of columns. Obtain numerical positive integer values for m and n as inputs from the user. Generate random numbers and scale them down to either a “0” or a “1” according to whether they represent “Clean” or “Dirty”, respectively. After filling the array with 0s or 1s, start at some random array position indicating the initial position of the vacuum cleaner. First check if at that current position, there is the presence of a “Dirt” or not determined by whether 0 or 1 is filled in at that initial position of the vacuum cleaner. If there is a “Dirt”, clean it, and if there is no “Dirt” do a No-operation. After this is done, generate random numbers modulo 4 to obtain random numbers 0, 1, 2, 3 indicating whether to take a left, right, up or down correspondingly.
