You are given a sequence of integers a=[a_1,a_2,...,a_n] of length n. Its subsequence is obtained... | instruction | 0 | 39,723 | 12 | 79,446 |
Tags: data structures, greedy
Correct Solution:
```
n=int(input())
s=sorted([[v,-i] for i,v in enumerate(map(int,input().split()))])
for _ in range(int(input())):
k,i=map(int,input().split())
ans=sorted(s[-k:],key=lambda x:-x[1])
print(ans[i-1][0])
