Title description

Given a binary representation of the nonnegative integers, converts it to a hexadecimal number,

Enter

How much input data set, the first data set number T, the T group data,
Each set of data a line, each behavior a binary integer (not including redundant leading 0), up to 1000,

O

Output corresponding hexadecimal number, in capital letters, said

CodePudding user response:

Well, you write is too messy, and how the circle hasn't exit turns ABCDEF? Might even consider not cycle

CodePudding user response:

Too complicated,

Read to a character array,
Two four hexadecimal said one hexadecimal, from the backward calculation,
ABCDEF directly by ASCII,
