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:
Following are the program in the Python Programming language.
#define function
def negative_num(num_list):
#set list type variable
nlist=[]
#set the for loop
for n in num_list:
#check negative numbers
if(n<0):
#add the value of n in list
nlist.append(n)
#return list
return nlist
#set new list type variable that store list
newl=[-5,8,-6,3,-4,9,-7]
#print and call the function
print(negative_num(newl))
<u>Output</u>:
[-5, -6, -4, -7]
Explanation:
Here, we define the function "negative_num" and pass an argument "num_list" in its parameter and inside the function.
- Set new list data type variable "nlist".
- Set the for loop which iterate as the list.
- Set the if conditional statement to check the value of the list is less than 0 then, add that negative values in the variable "nlist".
- Then, return the new list.
Finally, we set a variable "newl" which store the list of negative and positive numbers then, we print and call the function.
