Solution in Python (3.8.2) (judge verdict: Runtime Error)

# -*- coding: utf-8 -*-
# 整数の入力
N = int(input())
A = [int(a) for a in input().split()]
Q = int(input())
process = []
proc_append = process.append
for i in range(Q):
	proc_append(tuple(input().split()))
	process[i] = tuple(map(int,process[i]))

A.sort()

for b,c in process:
	if b in set(A):
		for i in range(N):
			if b==A[i]:
				begin = i
				break
		for i in range(begin,N):
			if b!=A[i]:
				end = i-1
				break
			if i==N-1:
				end = i
		for i in range(begin,end+1):
			A[i] = c
	print(sum(A))
