Round: Test
Experience: Given a marathon racer and an array of 5 elements having the time taken (t_i) and energy spent(e_i) for running 1 Km. He has to run a marathon of D Km and expending atmost E energy. Find the minimum time required to run the marathon. Once he starts a 1 Km sprint, he has to continue at the same speed till the 1 Km is complete.
Tips: Try Brute force, if nothing works.

I used a*e_1+b*e_2+c*e_3+d*e_4+e * e_5 <= E
and a+b+c+d+e = D

Solve these two equation and minimize a*t_1+b*t_2+c*t_3+d*t_4+e * t_5
