Reversing part of a string in Python -

-

let's have string stored in variable:

a = 'python'

now, a[2:4] returns th. how reverse part of string ht returned instead?

this tried:

print a[2:4:-1]

but returned empty string. know can store result of a[2:4] in new variable , reverse new variable. there way reverse part of string without creating new variable?

>>> = 'python' >>> a[2:4] 'th'

reverse substring using [::-1]

>>> a[2:4][::-1] 'ht'

or adjust indexes:

>>> a[3:1:-1] 'ht'

arrays - Algorithm to find ideal starting spot in a circle -

-
so problem have been debating such: your given array of integers representing circle. then, have pick spot in circle start. place start, compare value @ array number of steps took there , if steps less or equal number, include in final set. find place start have elements in set. ex, a=[0, 1, 2] if start @ index=0, then: a[0]=0 < =0 0 included a[1]=1 < =1 1 included a[2]=2 < =2 2 included final set: {0,1,2} if start @ index=1, then: a[1]=1 > 0 1 not included a[2]=2 > 1 2 not included here loop around a[0]=0 > 2 0 included final set: {0} if start @ index=2, then: a[2]=2 > 0 2 not included, here loop around a[0]=0 < = 1 0 included a[1]=1 < = 2 1 included final set: {0,1} so in trivial case, starting position index=0 best position results in final set elements. brute force method of finding obvious, trying find more efficient method. attempts far have been examine trying find max intersect of viable starting ranges calculated each element in arr...
