Max sum sub-array cumilative method

#1

for(i= 0 ; i<n ; i++){
for(j=i; j<n; j++)
{
sum= cumsum[ j ]-cumsum[ i-1 ];

}

}

If for first iteration i=0
then i-1=-1
so for cumsum[ i-1 ] with i=0 should give error???

#2

@abhayg1602 yes maybe give some garbage so you have to check that separately no issue

#3

prateek sir has written this code and it is working

#4

@abhayg1602 yes it may or may not give garbage in our compiler but in online coding comp it will always give run time error so you have to make sure i-1>=0

#5

I have tested it on many ide its working but ideally it should not??

#6

@abhayg1602 yes as i said it will give runtime error in cp competitions on submission
