S2[0i] is a scrambled string of S1[n-in] and S2[i+1n] is a scrambled string of S1[0n-i-1]. Further operations will be done in that array. The only difference is that shuffle () is used to perform the scrambling task, rather than sample () is used. Using this approach, we can keep the original string unchanged and get the new shuffled string in return. Since the string is immutable, we shall store the characters of the string in a character array ( say li ). Follow me on Twitter. The basic idea is to divide s1 (s2) into two substrings with length k and len-k and check if the two substrings s1 [0..k-1] and s1 [k, len-1] are the scrambles of s2 [0..k-1] and s2 [k,len-1] or s2 [len-k, len-1] and s2 [0..len-k-1] via recursion. The steps involved are: Find out the length of the word using the len function and then save it to some variable (say n). Using f- string.
