Top TCS NQT Hands-on Coding Questions with Solutions

Problem 1: Array Element Frequency Counting

Given an array of integers, find the frequency of each element and print the elements in ascending order with their counts.

// C++ Solution for TCS NQT Frequency Count
#include <iostream>
#include <map>
using namespace std;

void countFrequency(int arr[], int n) {
    map<int, int> mp;
    for(int i = 0; i < n; i++) {
        mp[arr[i]]++;
    }
    for(auto x : mp) {
        cout << x.first << " occurs " << x.second << " times" << endl;
    }
}

int main() {
    int arr[] = {10, 20, 20, 10, 10, 30, 5, 20};
    int n = sizeof(arr)/sizeof(arr[0]);
    countFrequency(arr, n);
    return 0;
}

Key Preparation Tips for TCS Digital Profile

1. Focus heavily on Data Structures: Arrays, Strings, Hashing, and Dynamic Programming.
2. Master String manipulation algorithms like palindrome verification, substring matching, and anagram checks.
3. Practice time management: Spend no more than 1.5 minutes per MCQ in the cognitive section.
