I wrote the supply code for a brand new utility on IOS, when writing there have been no errors, however once I ran the code, an error appeared on this place:
var t = readLine()!
var s = readLine()!
var len_s = s.rely
var t_lis = Set(t)
var c_s = Counter(s)
var c_t = Counter(t_lis[len_s])
var c_res = [String: String]()
var summ = 0
for e in c_s{
c_res[e] = [c_s[e], min( c_s[e], c_t[e] )]
summ += c_res[e][1]}
for i in (t.count-s.rely) + 1 {
if summ == len_s-1{
print(i)
break
}
if t[i] in c_res
if c_res[t[i]][1] > 0{
c_res[t[i]][1] -= 1
summ -= 1
}
if i+len_s < t.rely && t[i+len_s] in c_res
if c_res[ t[i+len_s] ][1] < c_res[ t[i+len_s] ][0]{
c_res[ t[i+len_s] ][1] += 1
summ += 1
}
else
print(-1)
}
Who can inform what’s flawed?
And does anybody know a high quality service for code evaluation? Which may make one code distinctive throughout a number of tasks. Thanks prematurely!
