Error coming in test cases when max sum includes the 0th element of the array

#1

for(int i=0;i<n;i++)
//here i is starting from 0.
//in the condition,
currentSum=cumsum[j]-cumsum[i-1]
//if(i==0) then cumsum[i-1] will be cumsum[-1]., that is not defined thus giving error.
can u explain how to fix it?

Hello @sidharth.delhi12_20344cb0d809bedb,

Just check if i is 0 or not like this,

currentSum = cumSum[j];
if(i!=0){
     currentSum -= cumSum[i-1]
}

I think this will work now
