PROGRAMMING:Duplicate data problem heboost
It's a common thing to find out the duplicate in a lot of data. Now we have to deal with many integers, in which there may be duplicate data.
You need to write a program to do this, read in the data, and check for duplicate data. If yes, output the three letters "yes"; If not, "no" is output.
###Input format:
The program will read the string of N integers [1 < = n < = 10000], separated by spaces. The range of these integers is [110000].
###Output format:
If there are duplicate integers, output:
yes
Otherwise, it outputs:
no
###Input example:
Here is a set of inputs. For example:
```in
1 2 3 1 4
```
###Output example:
The corresponding output is given here. For example:
```out
yes
```
