Harold and his homework
Harold and Dan are friends and study in the same class. One day, they strike a deal about completing Harold's homework.
The deal is that, for every piece of homework belonging to Harold which Dan completes, Harold will give Dan some money. The catch is that every piece of homework has a deadline associated with it and has to be completed within that deadline only.
It takes 1 unit amount of time to complete a homework. You have to help Dan find and return the maximum money he can earn.
Input Specification:
input1: The number of tasks
input2: An array representing money associated with each task input3: An array representing the deadline of each task
Output Specification:
Your function must return the maximum amount of money Dan can earn
Example 1:
input1: 3
input2: (20,54,41)
input3: (3,4,5)
Output: 115
Explanation:
Here, all the homework can be done as all have different deadlines and so maximum money is the sum of 20+54+41= 115.
A light source emits visible light of two wavelengths: λ = 430 nm and λ’ = 510 nm. The source is used in a double-
slits interference experiment in which L =1.50 m and d = 0.025 0 mm. Are there any locations on the screen where
the bright fringes from the two wavelengths overlap exactly?
