Alice is a kindergarten teacher. She wants to give some candies to the children in her class. All the children sit in a line and each of them has a rating score according to his or her performance in the class. Alice wants to give at least 1 candy to each child. If two children sit next to each other, then the one with the higher rating must get more candies. Alice wants to minimize the total number of candies she must buy.
arr = [ 4, 6, 4, 5, 6, 2]
She gives the students candy in the following minimal amounts: [1, 2, 1, 2, 3, 1]
She must buy a minimum of 10 candies.

candies has the following parameter(s):
• int n: the number of children in the class
• int arr[n]: the ratings of each student
• int: the minimum number of candies Alice must buy
The first line contains an integer, n , the size of arr.
Each of the next n lines contains an integer arr[i] indicating the rating of the student at position i .
• 1<= n <= 105
• 1 <= arr[i] <= 105
Sample Input 1:
Sample Output 1:
Here 1, 2, 2 is the rating. Note that when two children have equal rating, they are allowed to have different number of candies. Hence optimal distribution will be 1, 2, 1.

What’s in it for you?
The idea behind these programming contests is that we want you to learn while competing. Also we believe that it is alright to refer to tutorials, books and other materials, learn a concept and then apply the same to solve a problem during a contest. But it is not alright to copy other people’s solutions or seek other people’s help to solve a problem without understanding it.
The dividing line may seem to be thin but it can be captured by the spirit of learning. If whatever you are doing is making you learn while you do so, we tend to believe that it is alright. Our sole intention lies in making our users learn new concepts while competing. However, all the participants are expected to abide to

- The total time is the sum of the time consumed for each problem solved. The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submittal of the first accepted run plus 10 penalty minutes for every previously rejected run for that problem. There is no time consumed for a problem that is not solved.
