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 integers he removes from the two stacks. Nick is disqualified from the game if, at any point, his running sum becomes greater than some integer maxSum given at the beginning of the game. Nick’s final score is the total number of integers he has removed from the two stacks. This article shows the solution of the interview preparation problem…

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 which is useful to crack the placement interview. You can get more Interview Problems here. Find the maximum possible height of the stacks such that all of the stacks are exactly the same height. This means you must remove zero or more cylinders from the top of zero or more of the three stacks until…

A bracket is considered to be any one of the following characters: (, ), {, }, [, or ]. The coding problem is defined in Hacker Rank platform. The problem can expand your Data Structure knowledge, as well as can helps you to crack Interviews. Two brackets are considered to be a matched pair if the an opening bracket (i.e., (, [, or {) occurs to the left of a closing bracket (i.e., ), ], or }) of the exact same type. There are three types of matched pairs of brackets: [], {}, and (). If the set of brackets it encloses are not matched, then a matching pair of brackets is not balanced. For example, {[(])} is not balanced because…

In this post we will solve the Maximum Element Problem give by Hacker Rank. It will give you insight to solve any Data Structure Problem. You have an empty sequence, and you will be given N queries. Each query is one of these three types: Function Description Complete the getMax function in the editor below. getMax has the following parameters:– string operations[n]: operations as strings Returns– int[]: the answers to each type 3 query Input Format The first line of input contains an integer, n. The next n lines each contain an above mentioned query. Constraints 1 <= n <= 10^51 <= x <= 10^91 <= type <= 3 All queries are…

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 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 value of x is legal, calculate y(x). If not, write a suitable error message and quit.
