Given a string s containing only digits, return the lexicographically smallest string that can be obtained after swapping adjacent digits in s with the same parity at most once. Digits have the same parity if both are odd or both are even. For example, 5 and 9, as well as 2 and 4, h...
Return the lexicographically smallest string you can obtain after performing the above operation exactly once. A substring is a contiguous sequence of characters in a string. A stringxis lexicographically smaller than a stringyof the same length ifx[i]comes beforey[i]in alphabetic order for the f...
Return the lexicographically smallest string you can obtain by applying the above operations any number of times on s. A string a is lexicographically smaller than a string b (of the same length) if in the first position where a and b differ, string a has a letter that appears earlier in...
Find the lexicographically smallest string that starts at a leaf of this tree and ends at the root. (As a reminder, any shorter prefix of a string is lexicographically smaller: for example, “ab” is lexicographically smaller than “aba”. A leaf of a node is a node that has no children...
Return the lexicographically smallest equivalent string ofSby using the equivalency information fromAandB. Example 1: AB[m,p][a,o][k,r,s][e,i]"makkek" Example 2: A B [h,w] [d,e,o] [l,r]'o'S'd'"hdld" Example 3: A
Since there could be several different shortest ways, you should output the lexicographically smallest way. If the ball cannot reach the hole, output “impossible”. The maze is represented by a binary 2D array. 1 means the wall and 0 means the empty space. You may assume that the borders...
