      TCS Digital Interview Questions

      TCS Digital Interview Questions - TCS Interview Questions - Edureka

      The kind of Coding questions majorly asked in TCS Digital Interview are:

      Note that you will first be asked to choose the programming language of your preference so you have to answer the problem in your preferred programming language like C, C++, Java, Python etc.

      Q1)  Joseph is learning digital logic subject which will be for his next semester. He usually tries to solve unit assignment problems   before the lecture. Today he got one tricky question. The problem statement is “A positive integer has been given as an input.   Convert decimal value to binary representation. Toggle all bits of it after the most significant bit including the most significant   bit. Print the positive integer value after toggling all bits”.

      Constraints : 1<=N<=100

      Example 1 – Input : 10 -> Integer

      Output : 5 -> result- Integer

      Solution in C:

      #include <stdio.h> 
      using namespace std; 
      int main() 
      { 
      int n; cin>>n; 
      int k=(1<<(int)floor(log2(n))+1)-1; 
      cout<<(n^k); 
      } 
      

      Solution in Python

      
      import math
      n=int(input())
      k=(1<int(math.log2(n))+1)-1
      print(n^k)
      
      

      Q2)  Given an array Arr[] of size T, contains binary digits, where

      • 0 represents a biker running to the north.
      • 1 represents a biker running to the south.

      The task is to count crossing biker in such a way that each pair of crossing biker(N, S), where 0<=N<S<T, is passing when N is running to   the north and S is running to the south.

      Constraints: 0<=N<S<T

      Example 1- Input :

      • 5 -> Number of elements i.e. T
      • 0 -> Value of 1st element.
      • 1 -> Value of 2nd element
      • 0 -> Value of 3rd element.
      • 1 -> Value of 4th element.
      • 1 -> Value of 5th element

      Output : 5

      Solution in Python:

      
      n = int (input ())
      
      L =[]
      
      sum = 0
      
      c = 0
      
      for _ in range (n):
      
      a = (input ())
      
      if a:
      
      sum += c
      
      else:
      
      c += 1
      
      print (sum)
