Given a text string in UART, print it out such that all lower case letters become upper case and upper case letters become lower case. $($Please note from ascii chart that difference between lower case and upper case letters is exactly $32.$ That is if we add $32$ to $65($uppercase A$),$ it becomes $97($lowercase a$)).$For example: Input: ThIs hAs GoT tO Be TEdIOus Output: tHiS HaS gOt To bE teDioUS

Write in ARMv$7$
