Duplicate values in unsorted array
AskAI
Algorithms, Data Structures and Coding
This technical problem deals with finding duplicate values in an unsorted array. The function should return true if any duplicates are found.
Find the Index of a Target Value in a Sorted Array
AskAI
Algorithms, Data Structures and Coding
This function takes a sorted array of integers and a target value as input. It returns the index of the target value if it is present in the array, or -1 if it is not .
Return all possible subsets of a given set of distinct integers.
AskAI
Algorithms, Data Structures and Coding
This technical problem asks the programmer to return all possible subsets of a given set of distinct integers. The solution set must not contain duplicate subsets.
Binary search in a sorted array
AskAI
Algorithms, Data Structures and Coding
This problem deals with finding a target value in a sorted array using binary search. If the target value is present in the array, the function should return its index. If the target value is not present in the array, the function should return -1.
Validate a string containing only '(', ')' and '*'
AskAI
Algorithms, Data Structures and Coding
This function checks whether a given string is valid according to the rules defined above. A valid string must contain matching parentheses, with the left parentheses coming before the right parentheses, and '*' characters representing either a left or right parentheses or an empty string.
Sum of all integers in a list.
AskAI
Algorithms, Data Structures and Coding
The problem is asking for the sum of all integers in a list. An example input would be [1, 2, 3, 4, 5], and the expected output would be 15.
Remove all duplicates from a linked list.
AskAI
Algorithms, Data Structures and Coding
To remove all duplicates from a linked list, we can iterate through the list, keeping track of which values have been seen already. If we encounter a value that we have seen before , we can remove it from the list. Otherwise, we add it to our set of seen values and continue iterating.
