Coding problem3
there were 3 question in this question.. questions are from array string and linked list.. these 3 question were there. i was able to solve all three question
1. Next greater element
Easy
10m average time
90% success
0/40
Asked in companies
You are given an array 'a' of size 'n'.
Print the Next Greater Element(NGE) for every element.
The Next Greater Element for an element 'x' is the first element on the right side of 'x' in the array, which is greater than 'x'.
If no greater elements exist to the right of 'x', consider the next greater element as -1.
For example:
Input: 'a' = [7, 12, 1, 20]
Output: NGE = [12, 20, 20, -1]
Explanation: For the given array,
- The next greater element for 7 is 12.
- The next greater element for 12 is 20.
- The next greater element for 1 is 20.
- There is no greater element for 20 on the right side. So we consider NGE as -1.
Problem approach
by using help of stack data structure i was able to solve this question
2. Reverse Linked List

Asked in companies
Given a singly linked list of integers. Your task is to return the head of the reversed linked list.
For example:
The given linked list is 1 -> 2 -> 3 -> 4-> NULL. Then the reverse linked list is 4 -> 3 -> 2 -> 1 -> NULL and the head of the reversed linked list will be 4.
Follow Up :
Can you solve this problem in O(N) time and O(1) space complexity?
Problem approach
used three pointer approach
3. Check Permutation
Easy
15m average time
85% success
0/40
Asked in companies
You have been given two strings 'STR1' and 'STR2'. You have to check whether the two strings are anagram to each other or not.
Note:
Two strings are said to be anagram if they contain the same characters, irrespective of the order of the characters.
Example :
If 'STR1' = “listen” and 'STR2' = “silent” then the output will be 1.
Both the strings contain the same set of characters.
Problem approach
i used map data structure and comparing both map
