❓ Help Java Program about stack

[Justchillbruh122]

sana may makasagot nito.

Enter string -> (x-2 * (x+7))
output balance

enter string -> ((x+6 * (x-4) + (x+3)
output notbalance

algo

scan all characters in the string
if open parenthesis "(" push to stack
if close parenthesis ")" push to pop

after scanning
if stack is empty = balance
if stack is not empty = not balance

may nakita akong mga code sa google:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47
