Не мога да си открия грешката, ако мо же помощ. Имам 90/100.

Create a program that helps you keep track of a number array. First, you are going to receive the numbers оn a single line, separated by space, in the following format:

"{number1} {number2} {number3}… {numbern}"

Then you will start receiving commands until you read the "End" message. There are five possible commands:

• "Switch {index}"
  • Find the number on this index in your collection, if the index exists, and switch its sign (negative <-> positive).  
• "Change {index} {value}"
  • Replace the number on the given index with the number given, if the index exists.
• "Sum Negative"
  • Print the sum of all negative numbers.
• "Sum Positive"
  • Print the sum of all positive numbers.
• "Sum All"
  • Print the sum of all numbers.

In the end, print the positive numbers on a single line, keeping in mind that 0 is positive, separated by a single space in the following format:

"{number1} {number2} {number3}… {numbern}"

Input

• On the 1st line you are going to receive the numbers of the array (always integers), separated by a single space.
• On the next lines, until the "End" command is received, you will be receiving commands.

Output

• Print the tasks in the format described above.
