In Java how to write loop inside a loop for instence "for loop" inside a "while loop" can I have sample with code

What is the primary difference between a foreach loop and a traditional for loop in programming?

Using c++ Contact list: Binary Search   A contact list is a place where you can store a specific contact with other associated information such as a phone number, email address, birthday, etc. Write a program that first takes as input an integer N that represents the number of word pairs in the list to follow. Word pairs consist of a name and a phone number (both strings). That list is followed by a name, and your program should output the phone number associated with that name. Define and call the following function. The return value of FindContact is the index of the contact with the provided contact name. If the name is not found, the function should return -1 This function should use binary search. Modify the algorithm to output the count of how many comparisons using == with the contactName were performed during the search, before it returns the index (or -1). int FindContact(ContactInfo contacts[], int size, string contactName) Ex: If the input is: 3 Frank 867-5309 Joe…

Java Task Write a for loop that prints the characters stored in a String object backward. The String is entered by the user.  ***Use ch = phrase.charAt(i); to get the character that is in index i of the String phrase.**** For example The user enters “Good morning!” The printout should be “!gninrom dooG”.

Python’s for loop allows the programmer to add or remove items in the collection over which the loop is iterating. Some designers worry that changing the structure of a collection during iteration might cause program crashes. The remedy is to make the for loop read-only, by disallowing mutations to the collection during iteration. You can detect such mutations by keeping a count of them and determining if this count goes up at any point within the collection’s __iter__ method. When this happens, you can raise an exception to prevent the computation from going forward. In the arraybag.py file complete the following in the ArrayBag class: In the __init__ method, include a new instance variable named modCount, which is set to 0. In the __iter__ method include a temporary variable named modCount, which is set initially to the value of the instance variable self.modCount. Immediately after an item is yielded within the __iter__ method, you raise an exception if the values of the two mod…

we showed you the code#for two versions of binary_search: one using recursion, one#using loops. For this problem, use the recursive one.##In this problem, we want to implement a new version of#binary_search, called binary_search_year. binary_search_year#will take in two parameters: a list of instances of Date,#and a year as an integer. It will return True if any date#in the list occurred within that year, False if not.##For example, imagine if listOfDates had three instances of#date: one for January 1st 2016, one for January 1st 2017,#and one for January 1st 2018. Then:##  binary_search_year(listOfDates, 2016) -> True#  binary_search_year(listOfDates, 2015) -> False##You should not assume that the list is pre-sorted, but you#should know that the sort() method works on lists of dates.##Instances of the Date class have three attributes: year,#month, and day. You can access them directly, you don't#have to use getters (e.g. myDate.month will access the#month of myDate).##You may…
