( 605 ) H Balanced brackets PROGRAMMING *special 1900

B'A sequence of brackets is called balanced if one can turn it into a valid math expression by adding characters xc2 xab+ xc2 xbb and xc2 xab1 xc2 xbb. For example, sequences xc2 xab(())() xc2 xbb, xc2 xab() xc2 xbb and xc2 xab(()(())) xc2 xbb are balanced, while xc2 xab)( xc2 xbb, xc2 xab(() xc2 xbb and xc2 xab(()))( xc2 xbb are not. You are given a string which consists of opening and closing round brackets. Check whether it is a balanced bracket sequence. The only line of input contains a string between 1 and 100 characters long, inclusive. Each character in the string will be xc2 xab( xc2 xbb or xc2 xab) xc2 xbb. Output xc2 xabYES xc2 xbb if the bracket sequence is balanced, and xc2 xabNO xc2 xbb otherwise (quotes for clarity only).'...
