Provide tags and a correct Python 3 solution for this coding contest problem.
You are given two arrays A and B consisting of integers, sorted in non-decreasing order. Check whether it is possible to choose k numbers in array A and choose m numbers in array B so that any number chosen in the first array is strictly les... | instruction | 0 | 18,956 | 12 | 37,912 |

Correct Solution:
```
na, nb = [int(j) for j in input().split()]
k, m = [int(j) for j in input().split()]
a = [int(j) for j in input().split()]
b = [int(j) for j in input().split()]
if a[k - 1] < b[nb - m]:
print("YES")
else:
print("NO")
