How to Clear the TCS Elevate Wings 1 DCA Exam

How to Clear the TCS Elevate Wings 1 DCA Exam: The Elevates Wings 1 DCA program is a Direct Capability Assessment for TCS associates with 0–3 years of work experience. It evaluates fundamental knowledge in at least one digital technology like cloud, data science, machine learning, artificial intelligence, blockchain, etc.

Passing the DCA can increase your salary by 100%. To pass, you must excel in the Technical + Managerial + HR interview and the online test (aptitude, logical reasoning, verbal, coding).

The coding test has medium complexity. With practice, it is passable. Solving previous year's questions will help in the next TCS DCA coding test.

TCS DCA Coding Questions

Q1: Write a Python program to remove vowels a, e, i, o, u from a given string. Ignore consecutive vowels.

Example 1: Input: "hello world", Output: "hll wrld"

Example 2: Input: "automobile", Output: "tmobl"

Python Program:

 def removeVowels(str): vowels = ['a','e','i','o','u'] result = [char for char in str if char.lower() not in vowels] return ''.join(result) string = input("Enter string: ") print(removeVowels(string)) 

Q2: Write a Python program to find and display prime numbers from a given list of integers. Take number of integers and the integer list as input.

Example 1:


 5 2 5 7 9 11 

Output: 2 7 11

Example 2:


 4 1 4 9 16 

Output: No prime numbers

Python Program:

 num = int(input("Enter number of elements: ")) arr = list(map(int,input("\nEnter the numbers separated by space: ").strip().split()))[:num] print("Prime numbers are: ") for i in arr: if i > 1: for j in range(2, int(i/2)+1): if (i % j) == 0: break else: print(i) 

Parallel Columbus Problem

Problem Statement: Nobel laureate Erwin Schrödinger brought many Christopher Columbus from parallel universes into a grid of size n x m. He placed some people of America at (x,y) and you at (n,m). All Columbus start from (1,1). Those reaching America think it's India. Find how many different Columbus will reach you as India first.

Function: markgame(n, m, x, y)


  • n - number of rows in grid
  • m - number of columns in grid
  • x,y - coordinates of America people


  • 1 <= n,m <= 1000
  • 1 <= x <= n
  • 1 <= y <= m

Input Format:

First line contains n and m separated by space

Second line contains x and y separated by space

Sample Input 1:

 2 2 2 1 

Sample Output 1:


Explanation: Only path is (1,1) -> (2,1) -> (2,2). So answer is 1.

Python Program:

 def markgame(n, m, x, y): if x == 1 and y == 1: return 0 count = 0 for i in range(1, n+1): for j in range(1, m+1): if i == x and j == y: break if i == n and j == m: count+=1 return count n, m = map(int, input().split()) x, y = map(int, input().split()) print(markgame(n, m, x, y))
