There are numBottles water bottles that are initially full of water. You can exchange numExchange empty water bottles from the market with one full water bottle.

There is a programming language with only four operations and one variable X. Given an array of strings operations containing a list of operations, return the final value of X after performing all the operations.

You have been tasked with writing a program for a popular bank that will automate all its incoming transactions (transfer, deposit, and withdraw). The bank has n accounts numbered from 1 to n. The initial balance of each account is stored in a 0-indexed integer array balance, with the (i + 1)th account having an initial balance of balance[i].

You are given an array of integers nums. You are also given an integer original which is the first number that needs to be searched for in nums. You then do the following steps:If original is found in nums, multiply it by two (i.e., set original = 2 * original). Otherwise, stop the process. Repeat this process with the new number as long as you keep finding the number. Return the final value of original.

You are given a 0-indexed integer array nums, where nums[i] is a digit between 0 and 9 (inclusive).

You are given two integers numBottles and numExchange. numBottles represents the number of full water bottles that you initially have. In one operation, you can perform one of the following operations

You are given an integer array nums. Start by selecting a starting position curr such that nums[curr] == 0, and choose a movement direction of either left or right.

You are given a string s consisting of digits. Perform the following operation repeatedly until the string has exactly two digits:For each pair of consecutive digits in s, starting from the first digit, calculate a new digit as the sum of the two digits modulo 10. Replace s with the sequence of newly calculated digits, maintaining the order in which they are computed. Return true if the final two digits in s are the same; otherwise, return false.
