Alexa has two stacks of non-negative integers, stack a[n] and stack b[m] where index 0 denotes the top of the stack. Alexa challenges Nick to play the following game: In each move, Nick can remove one integer from the top of either stack a or stack b. Nick keeps a running sum of the… Read More »HackerRank Solution – Problem Solving – Game of Two Stacks
You have three stacks of cylinders where each cylinder has the same diameter, but they may vary in height. You can change the height of a stack by removing and discarding its topmost cylinder any number of times. This problem is given by Hacker Rank… Read More »HackerRank Solution – Problem Solving – Equal Stacks

The gain G of a certain microwave dish antenna can be expressed as a function of angle by the equation where θ is measured in radians from the boresite of the dish, and sinc x=sin x/x. Plot this gain function on a polar plot, with… Read More »The gain G of a certain microwave dish antenna can be expressed as a function of angle by the equation. Plot this gain function on a polar plot, with the title “Antenna Gain vs” in boldface.
y(x)=ln 1/(1 –x) for any user-specified value of x, where x is a number <1.0 (note that ln is the natural logarithm, the logarithm to the base e). Use an if structure to verify that the value passed to the program is legal. If the… Read More »Write a MATLAB program to evaluate the function:
