Permutations of all digits in a numberGiven an n-digit number(all digits are unique), write a working  code to generate permutations of all numbers possible using one or more digits from the input number.Eg: Input: 123Output:123121321233132123132213231312321

Given a string without duplicates, print all the permutations of the string in a lexicographically order.Input FormatFirst line of input contains T - number of test cases. Its followed by T lines, each contains a single string consisting only of lowercase Enghish alphabets.ConstraintsFor each test case, print the test case number as shown, followed by all the permutations of the string in a lexicographically order, separated by newline.Output Format1 <= T <= 1001 <= len(str) <= 8Sample Input 02algodsSample Output 0Test Case #1:agloagolalgoalogaoglaolggalogaolglaogloagoalgolalagolaoglgaolgoaloaglogaoagloalgogaloglaolagolgaTest Case #2:dssd

Given an integer N. Print the count of permutations for the numbers from 1 to N, considering that prime numbers should be placed at positions with prime indices (1 - based indexing). As the result might be a large number, print the output % 1e9 + 7.

PermutationSend FeedbackGiven two values, n and r, write a function to calculate the permutation (nPr) for n ≥ r ≥ 0. The function should return -1 if n < r or if n or r are negative. The program should include two functions: one to calculate the factorial of a number and another to calculate the permutation.Function Input:n (int): The total number of objects.r (int): The number of objects taken at a time for the permutation.Output:The function will return the calculated permutation (nPr) in integer format. Handle input cases where r is greater than n. The function will return "please enter n >= r >= 0".Sample Input 16 5 Sample Output 1720Sample Input 25 6Sample Output 2please enter n >= r >= 0
