修改前

function createArrayOfFunctions(y) {
    var arr = [];
    for(var i = 0; i<y; i++) {
        arr[i] = function(x) { return x + i; }

| Title: Next Fibonacci |
| Usage: Give some integers, the function NextFibonacci::nextFibonacci() will return the next fibonacci numbers which are|
| greater than input numbers. |
| P.S. the table of fibonacci numbers in this program starts by F1 = 1, instead of F0 = 0. |
| |
| Example: |
| arr[] = { 1,9,22 }; |
| nextFibonacci(arr);

Answer2

The following is the main algorithm in my answer1.

for (it2 = set2.begin(); it2 != set2.end(); it2++)
{
	bool isContained = false;

	for (it1 = set1.begin(); it1 != set1.end(); it1++)
	{
 if (*it1 == *it2)

| Title: Check Subset |
| Usage: Sequentially enter two sets of uppercase alphabet, then this prgram will show a result of 'True' or 'False', to |
| show you if the second set is a subset of the first one. |
| |
| Example: |
| Please enter set1: ABCD |
| Please enter set2: CD |
| True.
