zeroTriples.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then find all triples in the list that sum to zero. You can assume the list won’t contain any duplicates, and a triple should not use the same number more than once. For example:$ python3 zeroTriples.py124-123450 triples found $ python3 zeroTriples.py-3142-123451 triple found:1, 2, -3 $ python zeroTriples.py-91-3245-4-1-123454 triples found:-9, 4, 51, -3, 2-3, 4, -15, -4, -1
What is a string literal?
Ex: Use getline() to get a line of user input into a string. Output the line. Enter text: IDK if I'll go. It's my BFF's birthday. You entered: IDK if I'll go. It's my BFF's birthday. Search the string (using find()) for common abbreviations and print a list of each found abbreviation along with its decoded meaning. Ex: Enter text: IDK if I'll go. It's my BFF's birthday. You entered: IDK if I'll go. It's my BFF's birthday. BFF: best friend forever IDK: I don't know Support these abbreviations: BFF -- best friend forever IDK -- I don't know .

A for construct is an iterative loop that processes a list of items. As a consequence, it continues to process items as long as there are things to process. Is this a true or false statement?
In some circumstances, a class is reliant on itself. That is, one class's object interacts with another class's object. To accomplish this, a method of the class may accept an object of the same class as a parameter.The String class's concat function is an example of this situation. The method is called by one String object and receives another String object as an argument. Here's an illustration:str3 is equal to str1.concat(str2);The method's String object (str1) appends its characters to those of the String supplied as a parameter (str2). As a consequence, a new String object is returned and saved as str3. Create Java code to implement the conditions given.

statistics.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then print the mean, median, and standard deviation of the list. The mean is the average of the numbers. The median is the “middle” value if n is odd, or the average of the two “middle” values if n is even. The standard deviation is the average amount of variability For example: $ python3 statistics.py154102-12345mean: 7.75median: 7standard deviation: 5.909032633745278
