    java if-statement boolean-operations
    I’m writing code for a minesweeper project for class and one method is numAdjMines, which counts the mines around a cell in the array, each type of cell has a different value, like mines are -2, while mines with a flag on them are -4.

    binary computer-architecture circuit boolean-operations
    I have this project listen below and im not sure where to start maybe someone can give me a few pointers or perhaps point me in the right direction of starting this? Thanks!!Input: A, B = octal digits (see representation below); Cin = binary digitOutput: S = octal digit (see representation below); Cout = binary digitTask: Using binary FAs, design a circuit that acts as an octal FA. More specifically, this circuit would input the two octal digits A, B, convert them into binary numbers, add them

    php boolean-operations
    I’ve notice that when one of the two conditions in a php if statement is not true. You get an undefined index notice for the statement that is not true.
