A substring of s is a string obtained by taking out a non-empty contiguous part in s. For example, if s = `ababc`, `a`, `bab` and `ababc` a... | instruction | 0 | 75,730 | 0 | 151,460 |
"Correct Solution:
```
s = input()
k = int(input())
l = []
for i in range(len(s)):
for j in range(1, k+1):
l.append(s[i:i+j])
print(sorted(set(l))[k-1])
``` | output | 1 | 75,730 | 0 | 151,461 |
