Task $1.$ Implement your function to perform a one$-$time reversal on the input sequence

perform$\_$reversal$($data$,$ a$,$ b$)$ function implementation

Give a list of values data, and two indices a and b $($a $<$ b$),$ you must produce and return a new list that reflects a reversal of all the values from index a to b inclusive. For example, a call to

perform$\_$reversal$([0,5,4,1,3,2,6],2,5)$

should return the list $[0,5,2,3,1,4,6]$

Note: Make sure to keep the first value and last value in the input list always be same as the first value is always to be $0,$ and the last value is always to be the maximum. Just need to move the order of the intermediate values.
