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.
Input : 11 — Vlaue of n1
15 — value of n2
Output :

Similarly, choose the smallest second palindromic substring that leaves a third palindromic sub-string.
If there is no way to split the word into exactly three palindromic substrings, print “Impossible” (without quotes). Every character of the string needs to be consumed.
Cases not allowed –
After finding 3 palindromes using above instructions, if any character of the original string remains unconsumed.
No character may be shared in forming 3 palindromes.
Constraints
1 <= the lngth of input sting <= 1000
Input : First line contains the input string consisting of characters between [a-z].
Output :

Calculate the number of all such permutations.
As this number can be large, print it modulo (1e9 +7).
Constraints
0 <= low <= high <= 10^9
K <= 10^6.
Input
First line contains two space separated integers denoting low and high respectively
Second line contains a single integer K.
Output
Print a single integer denoting the number of all such permutations Input
First line contains two space separated integers denoting low and high respectively
Second line contains a single integer K.
Output
Print a single integer denoting the number of all such permutations
Input : 4 5

Your task is that given the location of the first tree that catches fire, determine how long would it take for the entire forest to be on fire. You may assume that the lay out of the forest is such that the whole forest will catch fire for sure and that there will be at least one tree in the forest
Input Format:
First line contains two integers, M, N, space separated, giving the size of the forest in terms of the number of rows and columns respectively.
The next line contains two integers X,Y, space separated, giving the coordinates of the first tree that catches the fire.
The next M lines, where ith line containing N characters each of which is either T or W, giving the position of the Tree and Water in the ith row of the forest.
Output Format:
Single integer indicating the number of minutes taken for the entire forest to catch fire
Input : 3 3
W T T
T W W
W T T

For example, R = 2 and N = 3
All possible seating arrangements are
(1,2) & (3)
(1,3) & (2)
(2,3) & (1)
Attendees are numbered from 1 to N.
Input Format:
The first line contains T denoting the number of test cases.
Each test case contains two space separated integers R and N, Where R denotes the number of round tables and N denotes the number of attendees.
Output Format:
Single Integer S denoting the number of possible unique arrangements.
Constraints:
0 <= R <= 10(Integer)
0 < N <= 20 (Integer)
Input : 1
2 5
Output :

Q4I highly advised to practice all the basics and standard program asked at freshers or experienced level job interview in TCS Digital. Practice our hand-picked coding interview questions asked in TCS Digital. You can programed the given question in any language, you can post your answer and same time you can review the other answer. It is always recommanded to write your own program first and then refer others answers. At this page we have covers all the TCS Digital coding questions in 2020 and previously asked in their Interview round or coding rounds.
