Sample Input 1 

1000 100
1000 1000
80 1
400 30

Sample Output 1 



Test Case 11: Top 1010 participants receive rupees 10001000 and next 9090 participants receive rupees 100100 each. So, total prize money =10⋅1000+90⋅100=19000=10⋅1000+90⋅100=19000.

Test Case 22: Top 1010 participants receive rupees 10001000 and next 9090 participants receive rupees 10001000 each. So, total prize money =10⋅1000+90⋅1000=100000=10⋅1000+90⋅1000=100000.

Test Case 33: Top 1010 participants receive rupees 8080 and next 9090 participants receive rupee 11 each. So, total prize money =10⋅80+90⋅1=890=10⋅80+90⋅1=890.

Test Case 44: Top 1010 participants receive rupees 400400 and next 9090 participants receive rupees 3030 each. So, total prize money =10⋅400+90⋅30=6700=10⋅400+90⋅30=6700.
