Given with the points (x1, y1, z1), (x2, y2, z2), (x3, y3, z3) and (x4, y4, z4) and the program must check whether the given points are coplanar or not. Points are said to be coplanar is they lie under same plane and if they are under different-2 planes than the points are not coplanar.Given below is an image containing four points and all are under same plane which is xy plane that means points are coplanarGiven below is an image containing four points and all are under different planes which shows points are not coplanarExampleInput-: x1 = 2, y1 ...

Given with an array of amount invested by multiple person and another array containing the time period for which money is invested by corresponding person and the task is to generate the profit sharing ratio.What is Profit Sharing RatioIn a partnership firm, profits and losses are shared between the partners depending upon the capital invested by them in the business. On the basis of that capital investment percentage we calculate the profit sharing ratio which shows the amount of profit which is to be given to each partner of a business.Formula − Partner 1 = capital invested * time period ...

Given a string input containing password characters, the task is to check the strength of the password.The strength of the password is when you tell that the password is whether easily guessed or cracked. The strength should vary from weak, average and strong. To check the strength we have to check the following points −Password must be at least 8 characters long.It must contain 1 lower case alphabet.It must contain 1 uppercase alphabetIt must contain a digitIt must contain a special character like : !@#$%^&*()>= 8))          Print "Strong"       else if ((hasLower || hasUpper) ...
