// Using the JavaScript language, have the function RunLength(str) take the str parameter being passed and return a compressed // version of the string using the Run-length encoding algorithm. This algorithm works by taking the occurrence of each 
// repeating character and outputting that number along with a single character of the repeating sequence. 
// For example: "wwwggopp" would return 3w2g1o2p. The string will not contain any numbers, punctuation, or symbols. 

// Input = "aabbcde"        Output = "2a2b1c1d1e"
// Input = "wwwbbbw"        Output = "3w3b1w"
