I have this below string in a variable
cutString=21222222222222222122222222222222
this string is nothing but hex values depicted as below
21:22:22:22:22:22:22:22:21:22:22:22:22:22:22:22
so what i want to achieve is swap the lower order with higher order values in the string
21222222222222222122222222222222
output:
12222222222222221222222222222222
let me give you another exaample
12345678901234567890123456789012
output:
21436587092143658709214365870921
also i need to do one more implementation
first i need to store this convertted output in one variable say nextString
later i need to introduce a space between each byte as below so that i can loop it in for loop and perform some operation..(PS: there shouldnt be an extra space at the end of string)
2 1 4 3 6 5 8 7 0 9 2 1 4 3 6 5 8 7 0 9 2 1 4 3 6 5 8 7 0 9 2 1
any help is deeply appreciated. thanks.
even if i can just learn how to introucde spaces, i can handle swapping in for loop by myself.
