Rob is fond of collecting coins but unfortunately,sometimes he has to sell a coin to get other coins.he puts all his coins one over the other in a column.

(0,i):Add coin with value i to the collection.

(1,0):sell a coin.

Selling a coin:For selling a coin ,he picks up the top coin in the coloumn if he constraint A is satisfied.Constraint A:Rob can only sell the coin if the coin collection value is more than Y.

Upon removal ,the coin collection value goes to the previous value.Initially,with 0 coins ,coin collection value is 0.

Adding a Coin:on adding a coin of value i to the collection the coin collection value increments via the following prodcedure.

If the coin collection had>=X value then current total value is X+i else X+2*i.

Rob needs to find and return the final value of coin collection after Q operations.

Note:Initially,the value X is 0 and not X.

Ex1:

i/p1:10(deciding increment)

i/p2:0(selling coins)

i/p3:1(no of operations)

i/p4:{{0,5}}

o/p:10

While using a computer a user the ALT-TAB key to switch between applications. The ALT-TAB window works on the principle of holding the ALT key for MRU listening. Hence the applications arrange themselves in such a way that the most recently used application will be the first them in the ALT TAB window and so forth.

You are the list of opened applications and the number of times that the user presses the ‘Tab key’ to switch between applications. Find the final arrangements of applications in the ALT-TAB window.

Example 1:

Input1:4

Input1:3

Input1: {1,2,3,4}

Output: {3,1,2,4}

Explanations are open .Holding the ALT key the user presses TAB key3 times. This pops up application number 3.hence 3 is the most active application in the ALT-TAB panel.

Example 2:

Input1:10

Input1:7

Input1:{4,1,3,7,6,8,5,2,10,9}

Output:{5,4,1,3,7,6,8,2,10,9}
