Consider the following function: public void bSearch(int[] A, int value, int start, int end) { if (end value) { return bSearch(A, value, start, mid); } else if (value > A[mid]) { return bSearch(A, value, mid+1, end); } else { return mid; } } The mutation program P' changes the part as shown below. } else if (value > A[mid]) { return bSearch(A, value, mid+2, end); } else { return mid; } A test input is given t1: {A = [2, 3, 5, 7, 10, 11], value = 6, start=0, end=5}. Which statement below best describes the mutant with regards to the test input? O a. t1 resolves mutant P O b. The mutant P' with regards to test input t1 is live.
: Design and implement a text-based Minesweeper game. Minesweeper is the classicsingle-player computer game where an NxN grid has B mines (or bombs) hidden across the grid. Theremaining cells are either blank or have a number behind them. The numbers reflect the number ofbombs in the surrounding eight cells. The user then uncovers a cell. If it is a bomb, the player loses.If it is a number, the number is exposed. If it is a blank cell, this cell and all adjacent blank cells (up toand including the surrounding numeric cells) are exposed. The player wins when all non-bomb cellsare exposed. The player can also flag certain places as potential bombs. This doesn't affect gameplay, other than to block the user from accidentally clicking a cell that is thought to have a bomb.(Tip for the reader: if you're not familiar with this game, please play a few rounds on line first.)

ANSWER IN JAVA: Write an application that inputs five numbers, each between 10 and 100, inclusive. As each number is read, display it only if it’s not a duplicate of a number already read. Provide for the “worst case,” in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user enters each new value.

The class Rectangle also has the following: //mutator methods void setlength (float len) } //B. length = len; H accessor methods float getLength() I return length; The following statement creates an array of Rectangle with size 2: Rectangle[] arrayRectangle= new Rectangle[2]; Is it correct if executing the following statements? What is the output? If it is not correct, write the correct one arrayRectangle. setLength (12.59); System.out.printin[rectangle Set.getLength()); arrayRectangle[1].setLength(4.15); System.out.println(arrayRectangle[1].getLength()): QUESTION 3: Use the following int array int[] numbers = { 42, 28, 36, 72, 17, 25, 81, 65, 23, 58} -Open file data.txt to write. to write the values of the array numbers to the file with the y numbers to get the values
