You are given a 'Nx3' 2-D array 'Jobs' describing 'N' jobs where 'Jobs[i][0]' denotes the id of 'i-th' job, 'Jobs[i][1]' denotes the deadline of 'i-th' job, and 'Jobs[i][2]' denotes the profit associated with 'i-th job'.

You will make a particular profit if you complete the job within the deadline associated with it. Each job takes 1 unit of time to be completed, and you can schedule only one job at a particular time.

Return the number of jobs to be done to get maximum profit.

Note :

If a particular job has a deadline 'x', it means that it needs to be completed at any time before 'x'.

Assume that the start time is 0.

For Example :

'N' = 3, Jobs = [[1, 1, 30], [2, 3, 40], [3, 2, 10]].

All the jobs have different deadlines. So we can complete all the jobs.

At time 0-1, Job 1 will complete.
At time 1-2, Job 3 will complete.
At time 2-3, Job 2 will complete.

So our answer is [3 80].

You have been given two strings 'STR1' and 'STR2'. You have to check whether the two strings are anagram to each other or not.

Note:

Two strings are said to be anagram if they contain the same characters, irrespective of the order of the characters.

Example :

If 'STR1' = “listen” and 'STR2' = “silent” then the output will be 1.

Both the strings contain the same set of characters.

Given an array of integers 'ARR’ of size ‘N’. Replace each element of this array with its corresponding rank and return the array.

The rank of an element is an integer between 1 to ‘N’ inclusive that represents how large the element is in comparison to other elements of the array. The following rules can also define the rank of an element:

1. It is an integer starting from 1.

2. The larger the element, the larger the rank. If two elements are equal, their rank must be the same.

3. It should be as small as possible.

For Example:

'ARR' = [4, 7, 2, 90]

Here, 2 is the smallest element, followed by 4, 7, and 90. 

Hence rank of element 2 is 1, element 4 is 2, element 7 is 3, and element 90 is 4.

Hence we return [2, 3, 1, 4].
