8.23腾讯技术研究类和数据分析笔试

第一题括号匹配，用了两种方法，第三个样例一直不对，提交了之后也只过了10%的case，求解哪里出错了呢？

附上我的辣鸡代码,思路没变，用了两种写法

s=")([]]([(](])))([]()()]([][[)[()[)]([[(])][][[[([)]"
left_round=0
left_square=0
ans=0
for x in s:
    if x=='(':
        left_round+=1
    elif x==')':
        if left_round<1:
            ans+=1
        else:
            left_round-=1
    elif x=='[':
        left_square+=1
    else:
        if left_square<1:
            ans+=1
        else:
            left_square-=1
ans+=left_round+left_square
print(ans)

strs=")([]]([(](])))([]()()]([][[)[()[)]([[(])][][[[([)]"
strs=input()
flag=1
stack_round=[]
stack_square=[]
ans=0
for x in strs:
    if x=="(":
        stack_round.append(x)
    elif x=="[":
        stack_square.append(x)
    elif x==")":
        if len(stack_round)==0:
            ans+=1
        else:
            stack_round.pop()
    elif x=="]":
        if len(stack_square)==0:
            ans+=1
        else:
            stack_square.pop()
print(ans,len(stack_round),len(stack_square))
ans+=(len(stack_round)+len(stack_square))
print(ans)
