We should create many PR request as many features/bug fixes/etc, if we want to solve 4 issues then we should create 4 separated PR

There are many function that have undesirable empty spaces like:

defTest():Boolean= {
// <- this type of spaces1==1// <- this type of spaces
}

Please remove them

There are many spaces that are missing between functions, like:

defTemp1():Unit= {
...
} // <- add space heredefTemp2():Unit= {
...
}
