Given a string 'S' and a list 'wordList' that consists of 'N' distinct words. Let 'Wi' denote word at index 'i' in 'wordList'. For each word 'Wi' in 'wordList', you need to determine whether it is present in string 'S' or not. Return a boolean array, where a boolean value at index ‘i’ represents whether the word ‘Wi’ is present in the string ‘S’ or not.

A thief is robbing a store and can carry a maximum weight of ‘W’ into his knapsack. There are 'N' items available in the store and the weight and value of each item is known to the thief. Considering the constraints of the maximum weight that a knapsack can carry, you have to find the maximum profit that a thief can generate by stealing items.

Note: The thief is not allowed to break the items.

For example, N = 4, W = 10 and the weights and values of items are weights = [6, 1, 5, 3] and values = [3, 6, 1, 4]. Then the best way to fill the knapsack is to choose items with weight 6, 1 and 3. The total value of knapsack = 3 + 6 + 4 = 13.

You have been given an integer ‘X’ and a non-decreasing sorted doubly linked list with distinct nodes.

Your task is to return the number of triplets in the list that sum up to the value ‘X’.

Given a list of cities numbered from 0 to N-1 and a matrix 'DISTANCE' consisting of 'N' rows and 'N' columns denoting the distances between each pair of cities, what is the shortest possible route that visits each city exactly once and returns to the starting city?
