Asked in companies
Given a string S containing digits from 2 to 9 inclusive. Your task is to find all possible letter combinations that the number could represent.
A mapping from Digits to Letters (just like in Nokia 1100) is shown below. Note that 1 does not map to any letter.
Problem approach
class Solution {
public:
void solve(string digits, string output, int index, vector &ans, string mapping[]) {
// basecase
if(index>=digits.length()){
ans.push_back(output);
return;
}
int number=digits[index]-'0';
string value=mapping[number];
for(int i=0;i letterCombinations(string digits) {
vector ans;
if(digits.length()==0){
return ans;
}
string output;
int index=0;
string mapping[10] ={"", "", "abc","def","ghi","jkl","mno","pqrs","tuv","wxyz"};
solve(digits,output,index,ans,mapping);
return ans;
}
};
2. Two Sum

Asked in companies
You are given an array of integers 'ARR' of length 'N' and an integer Target. Your task is to return all pairs of elements such that they add up to Target.
Note:
We cannot use the element at a given index twice.
Follow Up:
Try to do this problem in O(N) time complexity.
Problem approach
class Solution {
public int[] twoSum(int[] nums, int target) {
for (int i = 0 ; i < nums.length;i++ ){
for(int j = i + 1 ; j < nums.length ; j++){
if(nums[j] + nums[i] == target)return new int[]{i , j };
}
}
return null;
}
