IOCL Recruitment 2026 — Two Sum Target Pair Index (Optimal O(N) Hash Map)
[TCS NQT 2026 Campus Memory Question #1]
Given an array of integers `nums` and an integer `target`, return indices of the two numbers such that they add up to `target` in O(N) time.
Coding DSA Solution
vector<int> twoSum(vector<int>& nums, int target) {
unordered_map<int, int> mp;
for(int i=0; i<nums.size(); i++) {
int comp = target - nums[i];
if(mp.count(comp)) return {mp[comp], i};
mp[nums[i]] = i;
}
return {};

Deleitte Off Campus Big Hiring — String Palindrome Pointer Traversal Bug
[Cognizant 2026 Campus Memory Question #4]
The following function fails when checking palindromes for odd-length strings. Identify the fix required.
Automata Fix Solution
bool isPalindrome(string s) {
int left = 0, right = s.length() - 1;
while(left < right) {
if(s[left++] != s[right--]) return false;
}
return true;
}AThe code is already correct and optimal: O(N) Time, O(1) Space
BChange `while(left < right)` to `while(left <= right)`
CIncrement `left += 2`
DUse `s.substr()` recursion
