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.
There can be 2 types of Operations:
(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 coiin 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 emoval ,the coin collection value goes to the previous value.Initially,with 0 coins ,coin collection value is 0.
Adding a Coin:
on addong 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.
Example1:
input1:10
input2:0
input3:1
input4:{{0,5}}
output:10
Greedy Businesssman:
Sam is a greedy businessman who has opened N stores in a city.at various locations.
The locations of stores are stored in 1 2-Dimensional array.the coordinates of ith store are defined as follows:
starting point would be input[0][i] and ending location would be input[1][i].
for example:when i=0,input[0][0]=2 and input [1][0]=5,it means that the 0th store spans from 2 uniits to 5 units.
The greedy businessman wants to set up warehouse =s which can supply goods to these stores.
A warehouse can only be set up at a good location.A location is said to be good location if it is lying in the ranfe of [a,b],where a denotes the starting unit of a store and b denotes the end unit of any store S(a,b).
for example: a location ‘X’ is a good location with respect to the store (a,b) ifa<==X<=b.
Note:there can be more than one stores located at a particular.
Example1:
input1:2
input2:{{1,2},{3,5}}
output1:1
