/* Given below is a code snippet in C showing a function that increments the input
by 1 if the input is greater than 0 : 

int inc_by_1(int n){
  if(n<=0)
      return 0;
  return n+1
Write the complete program (to be run in Rapberry Pi Pico) where:
- The C Program should get the input from the user and call the assembly
function
- The assembly function should perform the increment based on the condition and return 
the result to the C program.
