TCS digital coding question with solution 2022-2023

TCS Digital Coding problem -1


 Problem Description -: Given an array Arr[ ] of N integers and a positive integer K. The task is to cyclically rotate the array clockwise by K.

Note : Keep the first of the array unaltered.

 

Example 1:

  • 5  —Value of N
  • {10, 20, 30, 40, 50}  —Element of Arr[ ]
  • 2  —–Value of K

Output :

40 50 10 20 30

Example 2:

  • 4  —Value of N
  • {10, 20, 30, 40}  —Element of Arr[]
  • 1  —–Value of K

Output :

40 10 20 30

 Python -

n=int(input())

arr=[int(i) for i in input().split()]

k=int(input())

rfirst=arr[0:n-k]

rsecond=arr[n-k:]

print(rsecond+rfirst)

  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 ...
