Problem 45508. AK Sorting according to given order

Conventional ascending order of one digit number is [ 0, 1, 2, ......9]. Now this order is changed and stored in vector a. For example in a vector a = [3 8 7 5 0 9 2 1 6 4], first element 3 denotes the lowest value equal to 0 like in conventional representation and last element 4 denotes the highest value equal to 9 in conventional representation. Another vector b is unsorted one. You need to sort the vector b according the new order expressed by vector a. For a given vector b =[ 2 4 5 5 3 3 3 9 0] the sorted sequence is [3 3 3 5 5 0 9 2 4] and which should be stored in another vector named c.

Example : a= [ 3 8 7 5 0 9 2 1 6 4] % In this order '3' is considered as the smallest number and '4' is considered as largest number. b= [ 2 4 5 5 3 3 3 9 0] % This sequence is to be sorted according to the order in 'a'.

therefore, The should be, c=[3 3 3 5 5 0 9 2 4]

Comment: Consider both a & b are made using the digits from 0 to 9 only
