Answer:
public static String repeat(String text, int repeatCount) {
if(repeatCount < 0) {
throw new IllegalArgumentException("repeat count should be either 0 or a positive value");
}
if(repeatCount == 0) {
return "";
} else {
return text + repeat(text, repeatCount-1);
}
}
Explanation:
Here repeatCount is an int value.
at first we will check if repeatCount is non negative number and if it is code will throw exception.
If the value is 0 then we will return ""
If the value is >0 then recursive function is called again untill the repeatCount value is 0.
Answer:
The most straight forward way to do it: in general string are zero index based array of characters, so you need to get the length of the string, subtract one and that will be the last character, some expressions in concrete languages would be:
In Python:
name = "blair"
name[len(name) - 1]
In JavaScript:
name = "blair"
name[name.length - 1]
In C++:
#include <string>
string name = "blair";
name[name.length() - 1];
Answer:
Pre-order: Lisa, Bart, Homer, Flanders, Marge, Maggie, Smithers, Milhouse
In-order: Bart, Flanders, Homer, Lisa, Maggie, Marge, Milhouse, Smithers
Post-order: Flanders, Homer, Bart, Maggie, Milhouse, Smithers, Marge, Lisa
Explanation:
The required orders are mentioned.
Friends can challenge us, confuse us, and sometimes, we might wonder why we bother. But friendship is as important to our wellbeing as eating right and exercising. What’s more, friendships help us grow through each year of our lives.
The friends we meet in school teach us how to be patient, wait our turn, reach out, and try new hobbies. When we move into young adulthood we learn more about taking responsibility, finding a career path, and seeking out people as mentors.
As we continue into our 40s and beyond, we learn to weather the ups and downs in life, and once again friends provide a sounding board and place for us to grow. Friendship is key to our success with all our relationships and it can create a sense of purpose in our lives.
The people we bring into our lives as friends will show us how to forgive, laugh, and make conversation. The basic components of any relationship, from our marriage to our coworkers, are all founded in friendship. We learn how to interact with people because of our friends, even the ones that are opposite from us or share a different worldview.
We don’t just talk with others but learn from them. We understand the process of meeting new acquaintances and finding out what makes them tick. These people help push us out of our comfort zones while still providing a safe emotional space for us to be totally ourselves.
One of the most overlooked benefits of friendship is that it helps keep our minds and bodies strong. In fact, it’s as important to our physical health as eating well and keeping fit. A recent Harvard study concluded that having solid friendships in our life even helps promote brain health.
