For any element in keysList with a value greater than 100, print the corresponding value in itemsList, followed by a space. Ex: If keysList = {42, 105, 101, 100} and itemsList = {10, 20, 30, 40}, print:20 30 Since keysList.at(1) and keysList.at(2) have values greater than 100, the value of itemsList.at(1) and itemsList.at(2) are printed.
#include <iostream>#include <vector>using namespace std;
int main() { const int SIZE_LIST = 4; vector<int> keysList(SIZE_LIST); vector<int> itemsList(SIZE_LIST); unsigned int i;

- Q8 Hive Minds: Migrating Birds You again control a single insect, but there are B birds flying along known paths. Specifically, at time t each bird b will be at position (x¿(t), Yb(t)). The tuple of bird positions repeats with period T. Birds might move up to 3 squares per time step. An example is shown below, but keep in mind that you should answer for a general instance of the problem, not simply the map and path shown below. Your insect can share squares with birds and it can even hitch a ride on them! On any time step that your insect shares a square with a bird, the insect may either move as normal or move directly to the bird's next location (either action has cost 1, even if the bird travels farther than one square).arrow_forward3. Card Flipper: You walk into a room, and see a row of n cards. Each one has a number x; written on it, where i ranges from 1 to n. However, initially all the cards are face down. Your goal is to find a local minimum: that is, a card i whose number is less than or equal to those of its neighbors, xj-1 = X; <= Xj+1. The first and last cards can also be local minima, and they only have one neighbor to compare to. There can be many local minima, but you are only responsible for finding one of them. Obviously you can solve this problem by turning over all n cards, and scanning through them. However, show that you can find such a minimum by turning over only O(log n) cards.arrow_forwardpublic void OnSend(View v){ String phoneNumber = number.getText().toString(); String smsmessage = message.getText().toString(); if(phoneNumber == null || phoneNumber.length() == 0 || smsmessage == null || smsmessage.length() == 0){ return; } if(checkPermission(Manifest.permission.SEND_SMS)){ SmsManager smsManager = SmsManager.getDefault(); smsManager.sendTextMessage(phoneNumber, null, smsmessage, null, null); Toast.makeText(this, "Message sent", Toast.LENGTH_SHORT).show(); } Question 2: Explain the following code: button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { FragmentManager fm = getSupportFragmentManager(); FragmentTransaction ft = fm.beginTransaction(); XFragment xfragment = new XFragment(); ft.add(R.id.Main_fragment, xfragment);…arrow_forward
- Computer Science This is a codingbat problem. Please answer in Java and do not change the starter code. You have been asked to write the game of tic tac toe. In the first version of the game, we will only be comparing horizontally for a win. A win is determine by all of the elements in a row either being an X or an O. You need to return a String with the winner or TIE if there is no winner. ticTacToe(["X", "O", "O"], ["X", "O", "O"], ["X", "X", "X"]) → "X"ticTacToe(["X", "O", "X"], ["X", "X", "O"], ["O", "O", "O"]) → "O"ticTacToe(["X", "O", "X"], ["X", "X", "O"], ["O", "X", "O"]) → "TIE" public String ticTacToe(String[] top, String[] middle, String[] bottom) { }arrow_forward1- Let A = [2: 0.5: 4],and B=B(2:4).
