Doubt in my code for Activity Selection Problem

#1

I am getting the correct output, but I didn’t pass the test case 0. I want to know where I’m doing wrong in my code.

Crosscheck with this case:
1
25
37 45
75 76
76 91
64 78
10 53
13 24
94 99
89 92
82 84
77 87
65 73
55 77
43 99
32 37
90 95
30 53
97 99
77 91
93 99
13 64
26 51
7 39
31 50
11 14
33 79

The output must be 8
It is formed by picking activities:
32 37
37 45
65 73
75 76
82 84
89 92
97 99
