The trees are positioned in a square grid with N rows (numbered from 1 to N from north to south) and N columns (numbered from 1 to N from west to east). The height (in metres) of each tree is an integer between 1 and N × N, inclusive. Magically, the height of all trees is unique. Bunga is standing on the northmost point of the park and wants to count the number of visible trees for each Column. Similarly, Lestari is standing on the westmost point of the park and wants to count the number of visible trees for each Row. A tree X is visible if all other trees in front of the tree X are shorter than the tree X. For example, let N = 3 and the height (in metres) of the trees are as follows6 1 87 5 32 9 4 On the first column, Bunga can see two trees, as the tree on the third row is obstructed by the other trees.

Write a Java application to create a class with attributes patient name, patient_ID, age, readings of blood sugar test stored in an array. Define methods to get the patient details, print their details and calculate highest, lowest and average blood sugar levels based on the readings recorded. And the code should have (Do you want to Continue for other patient Y/N?).

When you pass an array to a function, the computer passes the address of each of the array elements. 2. When an array is sorted in descending order, the first element in the array contains the smallest value and the last element contains the largest value. 3. The variables in an array are referred to as elements of the array. 4. Assigning initial values to an array is not required, but considered good programming practice. 5. Parallel arrays are two or more arrays whose elements are related by their position in the arrays. 6. You should not pass a one-dimensional array to a function. 7. Passing an array by reference is more efficient than passing it by value. 8.

A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]arrow_forward
