Cut the cake in half horizontally, then stack the halves and cut vertically twice.

• Cut the cake horizontally to get 2 equal halves.

• Stack the halves on top of each other and cut vertically to get 4 equal quarters.

• Finally, stack the quarters and cut vertically again to get 8 equal parts.

They will meet again after the starting point at a distance of LCM(x, y).

• The distance at which they will meet again is the least common multiple (LCM) of their speeds.

• For example, if A is running at a speed of 4 m/s and B is running at a speed of 6 m/s, they will meet again after 12 meters.

• Another example, if A is running at a speed of 3 km/hr and B is running at a speed of 5 km/hr, they will meet again after 15 km.

The wire crafted into a circle will have the minimum area.

• The circle has the smallest perimeter to area ratio compared to the equilateral triangle and square.

• The formula for the area of a circle is A = πr^2, where r is the radius.

• For the equilateral triangle, the formula is A = (√3/4) * s^2, where s is the side length.

• For the square, the formula is A = s^2, where s is the side length.

Swapping two numbers using different techniques and discussing possible test cases and errors.

• Using a temporary variable to swap the numbers

• Using arithmetic operations to swap the numbers

• Using bitwise XOR operation to swap the numbers

• Test cases: positive numbers, negative numbers, zero, large numbers, floating point numbers

• Possible errors: not using a temporary variable correctly, overflow/underflow with arithmetic operations, not handling edge cases

A program to determine if a given number is prime or not.

• Check if the number is less than 2, if so it is not prime

• Iterate from 2 to the square root of the number and check for divisibility

• If the number is divisible by any number other than 1 and itself, it is not prime

• If no divisors are found, the number is prime
