in C# thank you.

Patterns of Algorithms - multiple item selection * Expensive Christmas trees Christmas trees are sold on the Christmas market. Write a program that lists the trees that are more expensive than K Hungarian Forints. Input The first line of the standard input contains the count of trees (1≤N≤100) and a price (1≤K≤10 000). The next N lines each contain the price of a tree (1≤T≤10 000). Output The first line of the standard output should contain the count of expensive trees, and it should be followed by the indexes of expensive trees in increasing order (separated by a space). Example Input 6 5000 2500 5300 1900 2400 8800 5300 Output 3256
