TCS Digital Coding Problem -2


 Problem Description -:  Given two non-negative integers n1 and n2

For example:

Suppose n1=11 and n2=15.

There is the number 11, which has repeated digits, but 12, 13, 14 and 15 have no repeated digits. So, the output is 4.

Example1:

Input:

  • 11 — Vlaue of n1
  • 15 — value of n2

Output:

  • 4

Example 2:

Input:

  • 101 — value of n1
  • 200 — value of n2

Output:

  • 72
Python -

n1=int(input())
n2=int(input())
l=[]
c=0
for i in range(n1,n2+1):
    while i!=0:
        r=i%10
        l.append(r)
        i=i//10
    if not(len(set(l))<len(l)):
        c+=1
    l.clear()
    
print(c)

  Let's learn about list comprehensions! You are given three integers     and     representing the dimensions of a cuboid along with an integer   . Print a list of all possible coordinates given by     on a 3D grid where the sum of     is not equal to   . Here,   . Please use list comprehensions rather than multiple loops, as a learning exercise. Example All permutations of   are: . Print an array of the elements that do not sum to  . Input Format Four integers   and  , each on a separate line. Constraints Print the list in lexicographic increasing order. Sample Input 0 1 1 1 2 Sample Output 0 [[0, 0, 0], [0, 0, 1], [0, 1, 0], [1, 0, 0], [1, 1, 1]] Explanation 0 Each variable   and   will have values of   or  . All permutations of lists in the form  . Remove all arrays that sum to   to leave only the valid permutations. Sample Input 1 2 2 2 ...
