Every function must return a value: O Yes O No
Mad Libs are activities that have a person provide various words, which are then used to complete a short story in unexpected (and hopefully funny) ways. Write a program that takes a string and an integer as input, and outputs a sentence using the input values as shown in the example below. The program repeats until the input string is quit and disregards the integer input that follows. Ex: If the input is: apples 5 shoes 2 quit 0 the output is: Eating 5 apples a day keeps the doctor away. Eating 2 shoes a day keeps the doctor away.
Using C language
# Lists A and B of integers are in the input, each on a separate line. # Task: Substitute all occurrences of maximum in B by minimum of value of A. #Print modified B. Print only values separated by single spaces. 111 Example: Input 3 23452345 2 3 4 5 55 20 33 11 55 33 11 33 44 44 55 Output

Please help me solve this problem C. Chess Boundary Positions: Write a program called chess_pos.py On a chessboard, positions are marked with letters between a and h for the column and a number between 1 and 8 for the row. Give a 2 character input string with a letter (a-h) and a number (1-8), print "Corner" if the value indicates a square on a corner. Print "Border" if the value indicates a square on an edge of the board. Otherwise, print "Inside".
In Python, strings are mutable. True or False
Java: User enter 20 strings, any string start with "b" or "B" should be printed on the screen
