I am experiencing an error - "Max Buffer reached: Too much information has been written to stdout." What should I do?

According to my code, u = [1, 3, 4, 7, 9, 10, 13, 15, 19, 21, 22, 27, 28, 31, 39, 40, 43, 45, 46, 55, 57, 58, 63, 64, 67, 79, 81, 82, 85, 87, 91, 93, 94, 111, 115, 117, 118, 121, 127, 129, 130, 135, 136, 139, 163, 165, 166, 171, 172, 175, 189, 190, 193, 202, 243, 244, 247, 256, 283, 364]
test1(10) = 22(index = 10)
test2(20) = 57(index = 20)
.
test4(50) = 189(index = 50) which is not equal to 175(index = 49)
How?

python 2.7

In testing(dbl_linear(50), 175), it shows '189 should equal 175'. I think it is referring to index 49,as in list index starts from 0, but in other test cases, it is working fine. So, can you check.

Can you explain how it comes '1A' in the example?
