# CUTSTICK - EDITORIAL

 0 PROBLEM LINK: Practice Author: Rupanjan Hari Tester: Rupanjan Hari DIFFICULTY : Easy PREREQUISITES : Math QUICK EXPLANATION You are given N sticks, where the length of each stick is a positive integer. A cut operation is performed on the sticks such that all of them are reduced by the length of the smallest stick. Suppose we have six sticks of the following lengths: 5 4 4 2 2 8 Then, in one cut operation we make a cut of length 2 from each of the six sticks. For the next cut operation four sticks are left (of non-zero length), whose lengths are the following: 3 2 2 6 The above step is repeated until no sticks are left. Given the length of N sticks, print the number of sticks that are left before each subsequent cut operations. Note: For each cut operation, you have to recalculate the length of smallest sticks (excluding zero-length sticks). EXPLANATION To make the problem look easy, I have divided the program into functions of appropriate name. Arrays: arr[] - Primary array that receives the input size of each stick tag[] - The array that keeps a count on which sticks are being cut, once cut the tag[index] value changes to 1 otherwise 0 Functions: void cut(int a[],int n,int tag[]) - Cuts the sticks with the minimum value in the primary array that it receives through a[]. int min(int a[],int n,int tag[]) - Finds the minimum size among all the sticks. void count(int a[],int n) - Counts the no. of sticks cut. int equal(int a[], int n) - Operates the loop until all sticks are cut.
