Answer:
for ( initialization; condition;increment)
{
code goes here;
}
in python:
for i in list/range:
code with proper indentation
By initialization above we mean, like int i=0; etc.
By condition like i<10;
and by increment it means like i++, ++i or i+=1; etc
And in python, i can be an integer value if the range is mentioned, and it can be an item of a list if the list is used. We can also use an array, string and various other data structures in python. like we can have characters in a string and so on.

Following are the code in the PHP Programming Language:
<u>foreach ($country_codes as $code => $name) {
</u>
Explanation:
The following option is true because the Foreach statement only works on the objects and array and this statement is good for accessing the key and value pairs from the array.
So, that's why to print following associative array through echo statement we use the Foreach loop statement with following right condition.
<u>syntax</u>:
foreach (array as value)
{
code or body to execute;
}

Answer:
B - array; hash
Explanation:
Arrays store elements of the same data type in a list. Every element in the array is assigned a unique integer (starting at 0). You are able to access/process an element by using its assigned integer. Hashes are similar in the fact that they also store data. The difference is that each element is assigned an object type (instead of an integer), making it a collection of key pairs, as such you would typically not use this to process elements efficiently.
Answer:
Explanation:
The following pseudocode for this method using operations of the ADT list would be the following
swap(aList, indexI, indexJ) {
initialize temp_variable = Retrieve(indexI, aList)
Insert(Retrieve(indexJ, aList), indexI, aList)
Insert(Retrieve(indexI, aList), temp_variable, aList)
}
This code basically saves the aList index of i , into a temporary Variable. Then it sets the aList index of i to the value of the element in index of j. Then it does the same for the index of j with the tem_variable. If we assume that the indexes of i and j exist, then it can crash our entire program if those indexes are missing from the list when we try to access them.
