While calling the function, we obviously have to pass the array and indexes as 0 and length-1. The While loop loops through a block of code as long as a specified condition is true. A permutation of integers 1,2, …, n is called beautiful if there are no adjacent elements whose difference is 1. Below is an output printing all permutation for an array [1,2,3,4]. Algorithm. A factor is an integer that can be divided evenly into another number. Expected output: [1, 2, 3, 4, 5, 6, 7, 8, 9] STEP 1: START STEP 2: DEFINE n, r, per, fact1, fact2 STEP 3: PRINT n, r STEP 4: fact1 =n STEP 5: REPEAT STEP 6 UNTIL i>=1 STEP 6: fact1 = fact1*i STEP 7: DEFINE number STEP 8: SET number = n - r STEP 9: fact 2 = fact2*i STEP 10: SET per = fact1/fact2 STEP 11: PRINT per STEP 12: END Java Program For example, to generate the sequence of multiples of some number n, just take P = 1, Q = n, and initial value 0.
