Published by Andrew Rosenwinkel in

Create a function that takes a single string as argument and returns an ordered array containing the indices of all capital letters in the string.

Examples

IndexOfCapitals("eDaBiT") ➞ [1, 3, 5]

IndexOfCapitals("eQuINoX") ➞ [1, 3, 4, 6]

IndexOfCapitals("determine") ➞ []

IndexOfCapitals("STRIKE") ➞ [0, 1, 2, 3, 4, 5]

IndexOfCapitals("sUn") ➞ [1]

Notes

  • Return an empty array if no uppercase letters are found in the string.
  • Special characters ($#@%) and numbers will be included in some test cases.
  • Assume all words do not have duplicate letters.
