Given an array, find two elements whose sum equals the target number (two sum).
Use a hash table to store the difference between the target and each element in the array.
Iterate through the array and check if the current element exists in the hash table.
If it does, return the current element and the corresponding value in the hash table.
If it doesn't, add the difference between the target and the current element to the
The task is to find the repeated and missing numbers in an array of integers.
Iterate through the array and mark the visited numbers by changing the sign of the element at the corresponding index.
If a number is already negative, it means it is a repeated number.
The missing number can be found by checking the index of the positive number.
Alternatively, we can use a hash set to keep track of visited numbers and find the m...

A recursive function to check if a number is prime or not.
Create a function that takes a number as input.
Check if the number is less than 2, return false.
Check if the number is 2, return true.
Check if the number is divisible by any number less than it, return false.
If none of the above conditions are met, call the function recursively with the number minus 1.
To reverse a linked list, we need to traverse the list and change the direction of the pointers.
Create three pointers: prev, curr, and next
Initialize prev to null, curr to head of the linked list, and next to null
Traverse the list and change the direction of the pointers: next = curr.next; curr.next = prev; prev = curr; curr = next;
Set the new head of the linked list to prev
It is not possible to stop man in the middle attack over an insecure communication line without using any kind of encryption.
Without encryption, the communication line is inherently insecure and vulnerable to man-in-the-middle attacks.
One possible solution is to use a secure communication line, such as a VPN or a dedicated private network.
Another solution is to use digital signatures to verify the authenticity of the c...

Heap and stack memory are two types of memory allocation in a program. Local variables are stored in stack memory. Memory tables are used to track memory allocation.
Heap memory is used for dynamic memory allocation, while stack memory is used for static memory allocation.
Local variables are stored in stack memory and are only accessible within the scope of the function they are declared in.
Memory tables are used to kee...
