Find the Duplicate Number Given an array nums containing n + 1 integers where each integer is between 1 and n (inclusive), prove that at least one duplicate number must exist. Assume that there is only one duplicate number, find the duplicate one. Note: You must not modify the array (as...

InJava While loop, condition is tested at the beginning of the loop and if the condition is True then only statements in that loop will be executed. So, While loop executes the code block only if the condition is True. InJava Do While loop, condition is tested at the end of the loop...

Design an algorithm to find the maximum profit. You may complete as many transactions as you like (ie, buy one and sell one share of the stock multiple times) with the following restrictions: You may not engage in multiple transactions at the same time (ie, you must sell the stock before...
