70  +  40  =  110 // first student (70 40 150)
110 +  15  = 125  //second one      (99 15 400)
125 +  10  = 135  // third one (100 10 120),
  he is 15 min late, (he's to be free at 120)

i hope it helps.

does this mean third should start at 110 and second start at
110+10=120?

students should start the exam as fast as they are ready (by the order
of T1)
so second student cannot enter the room after third one ( i suppose ;)
)

if the input is
4
100 10 120
70 40 150
99 15 400
101 50 160
what's to output and why

Solution:

1st) #2 starting at 70 ending at 110
2nd) #3 starting at 110 ending at 125
3rd) #1 starting at 125 ending at 135  (a +15 shift)
4th) #4 starting at 135 ending at 185  (a +25 shift)

That way the answer should be 25

let's see

70  + 40 = 110 (70 40 150)
110 + 15 = 125 (99 15 400)
125 + 10 = 135 (100 10 120) 15 min late
135 + 50 = 185 (101 50 160) 25 min late

if examenator shifts the beginning of the exam by 25 minutes then
every student will pass the exam before T3.

Thank you hajime, I got AC.

70  +  40  =  110 // first student (70 40 150)
110 +  10  = 120  //second one      (100 10 120)
129 +  10  = 139  // third one (99 15 400),
 he is free at 139?
 wait =0;

Oleg i think
thirs student comes in queue before second
as his t1 is 99 and thirds is 100
agree?

Thank all the people above!
