To reverse a singly linked list, we simply need to iterate through the list and reverse the pointers of each node. This can be done in place, without creating a new list.
This problem requires the use of a binary search algorithm to find a target value in a sorted array. If the target value is found, the index of that value is returned. If the target value is not found, -1 is returned.
This problem involves searching for a given value in a sorted array of integers. If the value is found, the index of the target value is returned; if not, -1 is returned.
Given a 2D array of integers, find the longest path of consecutive integers starting from the top left corner of the array. The path can move in 4 directions: up, down, left , or right.
The twoSum function should return the indices of two numbers in an array that add up to a specific target number.
This problem deals with finding a target integer within a large array of integers. The function should return the index of the target integer if it is found, or -1 if it is not found .
This problem deals with finding the shortest path between two vertices in a graph. A data structure is needed that can efficiently find this path.
Given a 2D array of integers, this problem looks for the longest path from the top left to the bottom right where each step only visits cells with values greater than or equal to the current cell.
