Stock Buy Sell Once
Given daily stock prices, compute the maximum profit you can achieve from buying once and selling once later.
Candy Distribution
Compute the minimum total candies needed so that every child gets at least one and children with higher ratings than neighbors get more candies.
Maximum Ice Cream Bars
Given costs of ice cream bars and coins, return the maximum number you can buy.
Patching Array
Given a sorted array of positive integers and a target n, find the minimum number of patches to make every number from 1 to n representable as a subset sum.
Painter Partition Problem
Given board lengths and k painters, find the minimum possible maximum total length a painter must paint.
Job Sequencing with Deadlines and Profits
Given jobs with deadlines and profits, choose a subset that maximizes profit while meeting deadline constraints.
Gas Station Circuit
Given gas and cost arrays for a circular route, determine the starting gas station index that allows a full loop, or -1 if none exists.
Jump Game Reachable
Given an array of non-negative integers where each element is the maximum jump length, determine if you can reach the last index.
