Let me count opening parens '(' in the string.

I'll copy the string and count carefully by processing in chunks.

String: "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()(((()((()((()()((()))()((()(()(((()((()())))()((()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()))())()(())(((()((()())))()(())()))())()(()"

Let me split into chunks of 50 and count '(' in each.

Let me write out the string with indices. I'll just count '(' character by character.

Chunk 1 (50 chars): "()((()(()((()()((()))()((()(()(((()((()())))()(())"
Let me count '(': 
( ) ( ( ( ) ( ( ) ( ( ( ) ( ) ( ( ( ) ) ) ( ) ( ( ( ) ( ( ) ( ( ( ( ) ( ( ( ) ( ) ) ) ) ( ) ( ( ) )
Position by position:
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:( 48:( 49:) 50:)
Count of '(': positions 1,3,4,5,7,8,10,11,12,14,16,17,18,22,24,25,26,28,29,31,32,33,34,36,37,38,40,45,47,48 = 30

Chunk 2 (next 50): "()))())()(())((()()((()(()((()()((()))()((()(()((" 
Let me get chars 51-100 from original.

Actually, let me approach this differently. Let me write the string in pieces and total.

Let me re-extract the string carefully. I'll split at clear points.

Full string:
S = "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()(((()((()((()()((()))()((()(()(((()((()())))()((()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()))())()(())(((()((()())))()(())()))())()(()"

Let me count total length and count of '(' simultaneously by going through carefully.

I'll break at every 20 chars:

P1 (1-20): "()((()(()((()()((()))"  -- wait that's 21. Let me do 20: "()((()(()((()()((()))" no.
"()((()(()((()()((()" - 20 chars
chars: ( ) ( ( ( ) ( ( ) ( ( ( ) ( ) ( ( ( ) - hmm let me recount
"(" "(" - hmm

Let me just very carefully go through. I'll mark each '(' with 1 and ')' with 0.

S = "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()(((()((()((()()((()))()((()(()(((()((()())))()((()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())((()))()(((()((()((()()((()))()((()(()(((()((()())))()(())()))())()(())(((()((()())))()(())()))())()(()))()))())()(())(((()((()())))()(())()))())()(()"

Let me try a different approach - I'll count by recognizable repeating patterns.

Let me define:
A = "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"
Let me check if this appears multiple times.

Actually let me just carefully count. I'll go char by char in groups of 10.

S broken into 10-char chunks:
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: ")))()(())(" 
48: "))))())()(" 
49: "()"

Hmm this is error-prone. Let me try yet another approach.

I'll use the fact that total length = ? and count of '(' + count of ')' = length.

Actually, given that the problem is just counting, let me very carefully type out the string with newlines every ~40 chars and count.

Let me copy original and segment:

Segment A: "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"
Length check and count '(':
( ) ( ( ( ) ( ( ) ( ( ( ) ( ) ( ( ( ) ) ) ( ) ( ( ( ) ( ( ) ( ( ( ( ) ( ( ( ) ( ) ) ) ) ( ) ( ( ) ) ) ( ) ) ) ( ) ) ( ) ( ( ) )
Let me number them:
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( 48( 49) 50) 51) 52( 53) 54) 55) 56( 57) 58) 59( 60) 61( 62( 63) 64)

So segment A has 64 chars. Let me verify: "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"
() = 2
(( = 4
() = 6
(( = 8
) = 9 - wait

Let me count length of A precisely:
"()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"
( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( - let me list each char:
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: (
48: (
49: )
50: )
51: )
52: (
53: )
54: (
55: )
56: (
57: (
58: )
59: )
60: (
61: )
62: (
63: )
64: )

Hmm, my segment A is "()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"
Position 1-2: ()
3-4: ((
5-6: ()
7-8: ((
9-10: )(  -- wait 

OK let me just write out the string and count every '(' very carefully.

"()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"

Reading left to right:
( - 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
)
)

So A has 36 '(' and 64 chars total (36+28=64). Let me verify ): 28 ')'. 

Actually let me recount the string A by typing it slow:
"()" + "((" + "()" + "((" + ")(" - no this isn't right either.

Let me just take the string char by char:
"()((()(()((()()((()))()((()(()(((()((()())))()(())()))())()(())"

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