Please help. I am getting WA in WALKFAST and I can’t seem to figure out why.
Problem: WALKFAST Problem - CodeChef

Thanks in advance!
It seems to give the wrong answer for the testcase:
1
14 8 4 8 6 89 13 73
-990 -971 -893 -794 -694 -248 -140 -40 317 328 387 582 783 916
Edit:
Simpler example:
1
8 1 8 1 4 92 70 45
-70 -56 -49 -7 -1 2 19 45
The answer should be 9239:
TIME JUST WALKING:
Start position: -70
End position: 45
Distance (metres): 115
Time taken to walk distance at 92 seconds per metre: **10580**
Start train station position: -70
Distance to walk from journey begin to start train station: 0
Time taken to walk to start train station: 0
We can reach the train station on time
TIME WALKING TO STATION THEN CATCHING TRAIN THEN WALKING REST OF THE WAY:
Time waiting for train to leave: 45
Start train station position: -70
End train station position: -7
Distance between train stations: 63
Time taken to travel this distance by train, going at 70 seconds per metre: 4410
Final end position: 45
Distance between end train station and final end of journey: 52
Time taken to walk this distance at : 92 seconds per meter: 4784
Total time: **9239**

You were right. I am an idiot. I missed multiplying a q to the train distance travelled.
But still. I am still getting wrong answers.
