复习差分

刚刚复习了一下差分，发现写的并不熟练，出现很多问题

n,m=[int(num) for num in input().split()]
nums=[int(num) for num in input().split()]
dp=[0 for i in range(n)]
dp[0]=nums[0]
for i in range(1,n):
    dp[i]=nums[i]-nums[i-1]
dp.append(0)#在数组最后面添加0，防止dp[-1]越界
for i in range(m):
    temp=[int(num) for num in input().split()]
    dp[temp[0]-1]+=temp[2]
    dp[temp[1]]-=temp[2]
res=0
for i in range(n):
    res+=dp[i]
    print(res,end=' ')
