Suppose we have a string s and a list of indices ind, they are of same length. The string s will be shuffled such that the character at the position i, moves to indices[i] in the final string. We have to find the final string.
So, if the input is like s = "ktoalak" ind = [0,5,1,6,2,4,3], then the output will be "kolkata"
To solve this, we will follow these steps −
fin_str := a list whose size is same as s and fill with 0
for each index i and character v in s, do
fin_str[ind[i]] := v
join each character present in fin_str and return
Let us see the following implementation to get better understanding −
def solve(s, ind): fin_str =  * len(s) for i, v in enumerate(s): fin_str[ind[i]] = v return "".join(fin_str) s = "ktoalak" ind = [0,5,1,6,2,4,3] print(solve(s, ind))
