Use a for loop to print the squares and cubes of all integers from $a$ to $b$ as required by the problem statement.

Since $b \leq 1 0^{4}$ , it follows that $b^{3} \leq 1 0^{12}$ . Use a $64$ -bit integer type.

Algorithm realization

Read the input data.

scanf("%lld %lld", &a, &b);

Print the squares of all integers from $a$ to $b$ inclusive in ascending order.

for (i = a; i <= b; i++)
  printf("%lld ", i * i);
printf("\n");

Print the cubes of all integers from $a$ to $b$ inclusive in descending order.

for (i = b; i >= a; i--)
  printf("%lld ", i * i * i);
printf("\n");

Java realization

import java.util.*;

public class Main
{
  public static void main(String[] args)
  {
    Scanner con = new Scanner(System.in);
    long a = con.nextLong();
    long b = con.nextLong();
    for(long i = a; i <= b; i++)
    	System.out.print(i*i + " ");
    System.out.println();
     
    for(long i = b; i >= a; i--)
    	System.out.print(i*i*i + " ");
    System.out.println();
    con.close();
  }
}

Python realization

Read the input data.

a, b = map(int,input().split())

Print the squares of all integers from $a$ to $b$ inclusive in ascending order.

for i in range(a,b+1):
  print(i*i, end = " ")
print()

Print the cubes of all integers from $a$ to $b$ inclusive in descending order.

for i in range(b,a-1,-1):
  print(i*i*i, end = " ")
print()
