The problem
Given a string, capitalize the letters that occupy even indexes and odd indexes individually, and return as proven beneath. Index “ will likely be thought-about even.
For instance, capitalize("abcdef") = ['AbCdEf', 'aBcDeF']. See check circumstances for extra examples.
The enter will likely be a lowercase string with no areas.
The answer in Golang
Possibility 1:
package deal resolution
import "unicode"
func Capitalize(s string) []string {
a, b := []rune(s),[]rune(s)
for i := vary a {
if ipercent2 == 0 {
a[i] = unicode.ToUpper(a[i])
} else {
b[i] = unicode.ToUpper(b[i])
}
}
return []string{string(a), string(b)}
}
Possibility 2:
package deal resolution
import "strings"
func Capitalize(st string) []string {
s1 := ""
s2 := ""
for i, c :=vary st {
if ipercent2==0 {
s1 += strings.ToUpper(string(c))
s2 += strings.ToLower(string(c))
} else {
s1 += strings.ToLower(string(c))
s2 += strings.ToUpper(string(c))
}
}
return []string{s1,s2}
}
Possibility 3:
package deal resolution
import "unicode"
func Capitalize(st string) []string {
outcome := make([]string, 2)
for p, s := vary st {
outcome[p % 2 & 1] += string(unicode.ToUpper(s))
outcome[p % 2 & 1 ^ 1] += string(unicode.ToLower(s))
}
return outcome
}
Check circumstances to validate our resolution

var ans = Capitalize(st)
